if you people do bad things, I use the word "bad" very loosely, just don't take it as it is... anyway, if you're gonna do those things, do it with a smile, don't do those things with like; "Ok I smoke this, but only after I've done this and that and that, besides I don't smoke everyday, I can smoke every 2 months it's ok, no problems, right... right?!"
if you think like that about the awesomeness you can't enjoy it with full speed imo...
if you do it, do it, no excuses just do it... sometimes I jug a bottle of tequila and smoke, not a good thing for training but if that shit controls me that; "I shouldn't do that", if that mentality is upon me, then I'm in no peace... do whatever you please, but allways be true to yourself. Then it is good no matter what it is that you do/take.
