I have posted most of this a number of times because a common problem is that photographers jump into Lightroom without understanding how it works.
I'll post it again as an answer to your question.
The key to working in Lightroom is organization.
The first thing to do is organize how you store images on your hard drives. I'll assume the images are stored on a non-OS internal drive or on external drives.
If you are using a Mac then name your image storage drive something that makes sense and can tell anyone that it is your image storage drive.
In Windows there is a problem in that Windows will automatically give any new or external drive that is plugged into the computer the next available drive letter.
I recommend that you change the drive letter of any image storage drive to something in the last half of the alphabet using Windows' Disk Management. When you do this the drive letter is sticky and as long as there are drive letters closer to the beginning of the alphabet available Windows won't reassign the drive letter. My internal and external image hard drives have drive letters between U and Z. Each drive has a unique name as well.
There is no communications between the OS file management software and Lightroom. To maintain your Lightroom organization you must move or rename images within Lightroom.
You also need to have a good cataloging scheme (mine duplicates my image storage scheme), and have an organized way to work in the Develop Module for your images.
Most of us think of the subjects of our images, not the dates we too took the images so a subject based file storage scheme makes sense to me. My scheme is based on stacked folders and names with the date as only part of the name for the actual folder that contains the images.
My Photos>France>Paris>Eiffel Tower 150813 where 150813 would be the date in the YYMMDD format. The Paris folder might also contain other folders such as Eiffel Tower 140602 and Louvre 1508012.
In Lightroom Collection Sets can contain other Collection Sets or be simple Collections so I use a stacked Collection Sets & Collections scheme, I don't start with a Collection Set called My Photos since LR itself serves as the top level Collection. The LR Catalog scheme for the above would have a Collection Set Called France, then a Collection Set called Paris and finally a simple Collection called Eiffel Tower 150813, etc. It would be (note I have indicated in parenthesis which is a Collection Set and which is a simple Collection):
France (Collection Set)>Paris(Collection Set)>Eiffel Tower 150813 (Collection) plus Collections for Eiffel Tower 140602 and Louvre 1508012.
Lightroom also lets you make Collections for special purposes. For instance, if you wanted to print a book of images from a trip to France, a wedding, etc. you might create a Collection of just the images you want to put into the book. With the new face recognition capability of LR it is also easy to create Collections of people.
The beauty of placing the same image in multiple Collections is that the image is not copied since a Collection is just a list of the addresses of where the images are stored on the hard disk. Very little space is used on your hard disk for the list of addresses when you place the same image in multiple Collections.
You also have the option of renaming your actual image files. One way of naming them might be Louvre 1508012-001 through Louvre 1508012-999. Personally, I don't rename my RAW files but I rename and sequentially number the JPGs I Export for use on the web or on a phone or tablet.
Using a top down folder scheme lets me easily find images using image viewer programs such as FastStone or even the OS file explorer. The Collection Scheme does the same in Lightroom, and adding keywords expands the search capabilities in Lightroom, making it even easier to find a single image or similar images.
Organization is also important in the Develop Module. The Basic Panel controls are arranged in the top down order in that Adobe thinks is the best order to make adjustments, and it is a very good order to use, but not always the best.
The order in which you make adjustments can vary, depending on the image. A good rule to use is to always correct the worst thing first then go back to the top down order.
Here are some tutorials on the Lightroom Library Module.

One of the best editing work flows I have found is the Five Step Tango by Jack Davis.

Here is my modified version, but as I said earlier it is necessary to remain flexible in what order you apply changes to your images.
Five Step Tango for Lightroom by Jack Davis with Modifications
- X-Rite ColorChecker Passport Camera Calibration and/or WB then Crop. If desired you can adjust the WB & Tint for artistic purposes but I only do this after setting the correct WB using the ColorChecker Passport or a WB card.
- Auto - With a bit of tweaking this works about 80% of the time for "normal" images. If you don't like the results just smile and tweak the results or just hit Undo and make the adjustments manually. Note that the latest versions of LR have a much improved Auto mode but it is likely the image will still need tweaking.
- Exposure - Adjust this for the mid-tones, not the highlights or shadows.
- Check or set the Whites and/or Blacks by using Shift plus double clicking Whites and/or Blacks. You can also hold down the Alt (Option) key while moving the sliders - this will display only the pixels that are pure white or pure black as appropriate.
- Clarity
Shadows
Highlights
It is worth noting that adjusting any of the five exposure controls will have some effect on the other four. If you adjust the Highlights or Shadows after setting the Whites and Blacks you should recheck and tweak the Whites and Blacks if necessary.
- Vibrance
Contrast if necessary
- HSL - rarely
- Creative Sharpening unless the image will be edited in a second program such as Photoshop
Noise Reduction, Noise Ninja, etc. - rarely since I shoot mostly at ISO 100 or 200
- Lens Corrections (this can be done on import if desired or delayed till this step)
- Post-Crop Vignetting or Radial Gradient Filter for Vignetting
Add Grain - rarely
- Edit in Photoshop, etc. as needed.
