What pushes you to go full time with gambling(poker)?
I went full-time with betting, not poker

It kind of fell into my lap as explained earlier. I was making good money with betting, more than a regular job in modern slavery would have given me at that time, so why work for less money and more importantly less fun.
Do you have a day stable job before that?
Is/was gambling your only profession, or did you have other jobs also?
I never had a regular job, but kept on working in my students job after finishing my studies (I already turned "pro" during my studies):
I used to have a little job, which gave me a small steady income and also paid for my health insurance and things like that. I liked that job, since it put me away from my screens for some hours every week and sort of refreshed my mind. I never liked to spend the whole day in front of the computer, I always looked for some variety, which that job gave me, but also doing some sports, going out, doing this and that. I don't have that job anymore, so I am relying solely on my bets now, which is putting some pressure on I must confess.
Have you considered first on playing dice games and other luck-based one before you do jump on poker?
No, I never was into things like dice games, lucky me

I never had any contact with gambling until I was introduced to betting by a friend (see the story above somewhere, if you are interested).
Seems like a lot of professional poker players end up as traders, since they've already learned to avoid the emotional part of dealing with money.
I'll bet you've tried your hand at trading too.
Yes, good point with those poker pros. Once you understand how markets/tables work, get the dynamics behind it and also are not super dumb when it comes to maths, it's all pretty similar. You have the framework and already went through all the emotional hussle that comes with it. I have seen poker pros go betting pros and vice versa. I have yet to meet people that went from poker/betting pro to trading pro though, but they surely exist (like you).
Actually I only ever traded sports odds and nothing else.
I want to ask few more question/s but I guess it's going to be too much already. I appreciated your answers.
Just ask them. When I find the time, I will answer.
