The advice of an older man...
point 1, what you need to do In the short term you earn your living. During this time you consider exactly what you want from life, & then you go for it. Sounds to me playing fooball to you is an interest, albeit a strong one, but a hobby, & you treat it accordingly.
point 2, you can't let your mind go down this road & I'm talking about life, not just football. Driving is my work & 30 years ago I almost died behind the wheel. I put it out of my head & got back in my car as soon as I was able.
