I have never before taken up photography as a hobby, per se. But I did turn what was once a hobby, computers, into a vocation. This last summer, after over forty years of it: I'd had enough. Actually, I'd had enough years ago, but stuck it out because I'd no idea what else I'd do to earn a living.
I have no inclination to pursue computer-oriented stuff just for the fun of it any longer. Haven't had, for years.
My other hobbies, of which there've been many I've pursued over the years: Some I set aside for a while and repeatedly come back to. Others I've explored for a while, left and never touched again.
I cannot say how photography will pan out. I have semi-seriously pursued it several times in the past. Maybe this time it'll "take." We'll see.
If I'm being honest with myself: Many of the hobbies I've pursued in the past have been more about acquiring the toys of the hobby than the hobby, itself, I suspect. This time, with photography, I'm going to try to make it more about doing than acquiring.
