It will be a very big step.
You will probably adjust but you'll have to be EXTREMELY organized and look after your health, both physically and mentally.
I had two large 'time to become a man' moments in my life.
One was when I decided to become a professional poker player and was trying to 'live' off poker for 6 months without any external financial help. I was age 24 and it was that time where I had to take the plunge and see if I could actually do it as a full time job, otherwise I'd have to start a corporate job with some family connections- which was a great job, but not what I wanted to do.
The second moment was when I decided to purchase a business which was a cafe restaurant in a very high foot traffic area (basically the busiest in the state). I had been playing poker professionally for 3 years and doing well. I was good at cash games which is where I made my bread and butter (online, sometimes live in casino's if a large event was on that attracted recreational 'fish' as we call them). Even though I was a cash game specialist (texas hold em and Pot Limit Omaha), started trying tournaments and I ran very hot in tournaments which skyrocketed my bankroll and had won enough money to look for a business opportunity.
There was enormous risk involved at investing pretty much all my life savings and some borrowed money from my parents, into a business in which I'd never had experience. The location of this cafe/restaurant was just too good to pass up and it just made sense.
Anyway, 8 years later and the business is going well and I don't actually have to do too much work. I do get help from my family but we now have 34 staff, and we have an accountant and 2 store managers to do the roster and staff issues. I still do the ordering, manage the books with help by an accountant, and 'run' the business side of the operation but only spend 30 hours on a normal week as my 'work week'. The rest of the time I play online poker and basically do what I want.
Anyway, I think the reason I did these things was probably because I was young, energetic, and always knew if anything went wrong I could rebuild pretty quickly since I was only 24/25 years old.
Ask yourself, will I regret not taking this opportunity.
Opportunities are taken, not given.
If you think you'll enjoy it and not get too stressed out, and it won't affect your wellbeing, then roll the dice my man. You've got another 50 years of working life ahead of you and really, you have nothing to lose.
