Hello, My Problem Is Stability And Focus, Last Thing I

Hello, my problem is stability and focus, last thing I actually committed with my whole energy was rugby, I played it for 12 years, played for U17 and U18 national teams, had high hopes and success but, a spine injury made me quit the only thing I loved. I'm sanguine, good with communications, funny with dominant personality. I'm multi talented in many things but, I quit them right before the big breakthrough, same with relationships with opposite sex, the moment something nice is starting to happen I do something stupid like cheating.
