Found this website with motivational quotes something like SP also has. It's called 'Believe to Achieve' I really love what they have!
I saw this reading that I wanted to share, I'll re-type it here and just add a bleep where there was a naughty word.
"You're right. It is easier to eat pizza than to run on the treadmill. It's easier to turn to ice cream rather than people for supporters. It's easier to say '((bleep)) it, I give up' then to say it '((bleep)) this, I can do it.' So you know what? I'm not going to sit here and tell you day after day you can do this. If you don't believe you can, then you can't. That's the honest truth. You need to do this for you, and if you don't want it enough, than you sure as hell won't achieve it. So take the easy way out and remain unhealthy and continue to gain weight because you can't realize you are the only one hurting yourself. I didn't say it would be easy. I said it would be worth it."
