FWIW - I think your motivation for success is of the wrong kind.
To have a chance, it should already be an obsession, something you just can't stop getting yourself involved with, despite all the advice, good, bad or simply misplaced. It also helps your chances if you are young, single and might enjoy living in a squat for a while.
I think a lot of the arts are similar; consider the Rolling Stones: the two top guns did just that, without hot water and even an idea of getting rich or successful - they say - it was the lure of the blues. Period. Read Keef's book, Life. He could just as easily be writing about photography.
Negative advice? Maybe, but also realistic unless you are already loaded to the point that you can support yourself (hence the appeal of singularity) for a minumum of six months with nothing coming in. I got into this racket for myself after six years of working for other people and learning a tiny bit about how such businesses work. So, I had my six month's-worth of capětal, but even then, before it got better I ended up in the red, not because I didn't find work, but because ad. agencies used to stipulate three months after month of invoice as pay-day... banker to the rich, I was. And that was when work wasn't that tough to find. If you can survive that first period, it encourages and toughens you up, both qualities becoming essential as the clientele goes higher up the scale.
Depending on the genre in which you choose to work, you can have a wonderful life or just wish you'd thought of something else.
So, if you care enough to cast caution to the wind, go for it; if not, retain it as an interesting hobby without the pro-induced nervous tensions that never go away, even after you retire.
Thanks for sharing this, it was very insightful! To be fair, I am being realistic here and I won't be doing something as crazy as giving everything up just for this. The plan is to branch out and have a little taste of how the business goes..meanwhile I'll still keep my job to have a steady income. I think an obsession could potentially be a dangerous thing, in my opinion you need to think everything through clearly before making decisions.
But I guess we'll see what happens, maybe one day it will
become an obsession, and maybe then I'll give up everything
just to try and make it. Who knows.
