Knowing what I know now I wouldn't have followed a professional career for many years. I've recently transformed myself into a skinhead and have started immersing myself in the skinhead scene.
I know this isn't a career option but living your life true to yourself is worth so much. If I had been a skinhead years ago I probably would have enjoyed all that time in a blue collar job and been happy. Now I'm happy having the shit kicked out of me every Friday night - great times.
