Shoot less.
Do you realize how much (dollars and weight) your spending, let alone stress of managing it all? What do you plan to do with the image, eventually?
Whether pro or amateur, you should always have a goal in mind. Shooting a lot of pictures doesn't equate to good photography.
Whether it's computer files or just household "stuff" people seldom think of how much they are paying to store things.
Think about your mortgage and how much of your floor space is actually used by humans vs storing boxes and junk.
Not much really. Because hard drives take up little space (my NAS is about the size of about 2 video cassettes stacked). Actually most of my space is used up by furniture and camera gear (and a home studio).
The above also applies to time. Being focused saves time.
The thing is, is that many people don't really even think about backing up their photos while traveling (or even measures to reduce or eliminate lost photos). Many people try to travel light, and there is nothing wrong with that, but I mean really light, like no backup drives, no tablet, no laptop, nothing that could be used for backing up while traveling, and I've heard some pretty sad stories about people losing all their photos from their vacation because they didn't back up their card because it had 256GB of storage and/or they only backed up every few months. In fact, backups in general, most people dont employ backup strategies until they suffered some loss, except for those who learn from other's mistakes and just start doing it from the start. But for some, they have to experience it before they realize the benefits and necessity for things like backing up photos. You've gone to all that trouble to go somewhere to photograph perhaps (atl east in the OP's case it sounds like) why not spend a little extra on some way to backup your photos each day?
