.....I`m 17 and I play for the past 2 years or so.....and there were times that I stood at home practising for about 9/10 hours and I didn`t feel tired.....because I was doing something that I LOVE and I was pretty happy to practise in front of my pc...... and know I`m feeling the consequences..I can play many stuff that in that days were impossible.....and now I have time for girlfriends..sex..... etc... lol... remember: all the hard work is worth it....
