Re: I am a fat piece of shit.
The reason your still a fat peice of shit is because your not passionate enough about this. You need a better reason to lose weight.
Get involved with people who are training for a competition (boxing,running,kickboxing... anything). Losing weight "because I got a bit too big" is rarely enough. There is almost always a bigger motivation.
Know this: Your going to be this way for the rest of your life. Only YOU can change it. Everybody you meet will judge you as a lazy pussy for not having the balls. Do you really want to go through the rest of your life knowing this is what people think of you? Woud you not rather walk into a room knowing your in top physical condition and feeling great?
