BTCUSD used to tell people I'm a dog trainer (I was, i just didn't want them to try to hire me because of my health condition). Now, I tell them I'm a retired dog trainer, and they still want to hire me as a dog trainer. Trading full time is a challenge because people still want to hire you if you are good at something.
BTCUSD famous trader, Peter Brandt, suggests having at least two years of life savings, not including trading account, before quitting your job. I say one is OK, but you can never save too much. and there is nothing wrong with trading and working a real job until you're retired. Traders have this macho mindset; "i can do it all on my own." you don't have to do that.
