What line of work are planning to go into, return to? How will you represent the decade of pro sports betting on your resume?
I worked as a technical documentarist in the past and also in a managerial (non-technical) role for an online bookmaker. During the first three years of my pro betting career I also launched my own online sportsbook but that project failed miserably. Maybe I can use that to partially explain the huge gap but I am still undecided.
A strong desire for maths with an ability to tolerate programming, maybe look for a path into data science or machine learning. I see on this site or reddit or lobste.rs for free online courses for both all the time.
Regardless, I wish you luck and hope things go well.
1) I am finding sports betting difficult to scale, financially it is ok but not great. 2) Bookmakers are getting better and better every year. So am I, but I can imagine a scenario where they reach a stock-market like efficiency and it will be impossible to beat them (also, there is no growth like in stocks). I feel like I need to get some work experience under my belt and become more employable so that I have something to fall back on. 3) Bookmakers limit or ban winning players so there is the hassle of obtaining new identities (typically friends or family members who let you bet in their name) all the time. 4) I no longer like the industry and I am not proud of what I do. I live in central Europe where sports betting is legal but that is not the case everywhere else in the world. I have the dream of living in an English speaking country one day and that doesn't go well with my current "career". 5) I miss social interaction.
