let's see ...
self-harm
playing too much vidya during school which resulted in pretty bad grades
not staying in touch with my friends from school
breaking up with my gf of 5 years
not starting to lift weights sooner
not looking for a job straight away when i finished school
pretty much wasting 3 years of my life at university not really studying and just playing vidya and partying instead just to drop out
getting my shit together now but god damn i was a fucking retard for a good part of my life
