I gey what you are saying, about the fear and the photography itself. I guess while you have to take care of yourself, give yout eyes rest, eath healthy etc you should not get too much obsessed with "what happens if". What if you found out you have cancer next month, what if you were hit by a cat tomorrow.
You have found your passion so pursue it while you can, nothing is a given and we can not know what will happen tomorrow. What we can do is not to fear of what might or might not happen as fear so often a reason those things are happening in a first place. I am sure you will be allright mate. Cheers!
I know, you are totally right. I know I have a problem thinking about what if's and my wife tells me all the time to not worry about things that may or may not happen in the future. Thanks for your kind words, I really appreciate it :) Also, in the first paragraph of your comment, you said "What if you were hit by a cat tomorrow" and that made me laugh a lot hahaha. I'm sure you meant car, and I understood that, but I just couldn't get the image of some giant cat running into me at full speed out of my head.
Lol it seems a timely mistake to cheer up this sad mood a bit. Who knows, what might happen tomorrow? What if you were hit by a huge CAT tomorrow mate? What would you do?:)
