Is it hard to live as a photographer for profession in these days ?
Yes, very, especially if you're starting out! Chances are you'd make more money working in McDonalds than you would in the first three years starting out as a photographer.
Photography is generally a lifestyle business as opposed to a reliable profession. Sure you could make a good living from photography, but it's significantly more likely you'll make a modest, subsistence standard of living than a good one.
I guess it comes down to how much you want to be a photographer and if you're prepared to accept the likelihood of a lower standard of living than if you chose a different, more stable profession with higher average mean salary.
No one can tell you what to do. Just make sure if you do chose to give it a go, do it with your eyes open to the realities of the industry.
