I believe that it's vital to keep both - micro & macro vision in correct perspective when making a choice. Life is after all, a succession of choices viewed expertly in hindsight. Rearview vision is always 20/20. But we tend to go with tactical moves without demonstrating sufficient strategic intent. The successful ones tie one to the other.
So you want to be a photographer. A famous one at that, making greens by the load. It wont happen overnight unless the tooth fairy drops by and feels generous. You got to work at it. I'm in the process working 6 days on the regular job and skipping about here and there landing myself an assignment every now and then.
The first step was the toughest. I had more nervous nellies than I'd care to count.A very dear friend had me over shooting her nephews first birthday. I was too overwhelmed to ask for remuneration. She did her bit though. My only deal was that I'd shoot the images my way. Candid and natural. I got home with 485 images and was scared, still wondering if I could do justice to the post processing. Luckily, things turned out fine. Even today she sends assignments my way and still, I get Tongue tied asking for compensation.
But yeah, moving ahead of the first step, things slowed down. At first the high of the initial assignment kept me going. Then a lil despondence began to creep in as there were compliments on the photographs I posted on Facebook, but no assignments. A wait of 6 months ensued before I shot the next photograph, as a paid assignment. I questioned myself a lot in those 180 days and remained focussed on clicking for fun. It paid off in the end. Somewhere a young bride to be had seen my pics. She went out on a limb and we were on. Her Australian fiancé was a tad skeptical, but she tided over that. There's been no looking back ever since.
As a matter of principle, I take on only a couple of assignments a month. That ensures I can focus on both, the day job and my photography without being unfair to either.
I keep both the macro and micro pictures in my head all the time. Every step, no matter how small, brings me closer to my destination.
