Just came across a bunch of quotes I compiled a while back. Of course, I didn't take the time to write down who said them, so just know that none of them are mine... =)
"It doesn't matter how slowly you go, as long as you don't stop."
"Don't give up 5 minutes before the miracle."
"Sacrifice is giving up something good for something better."
"Some people dream of success. Others wake up and work hard at it."
"Sometimes there is no next time, no second chance, no time out. Sometimes it's now or never."
"Obstacles are those frightful things you see when you take your eyes off your goal."
"Can't is a word you use when you don't want to."
"Improvements are made over time, not overnight."
"Start by doing the necessary, then the possible, and suddenly you are doing the impossible."
"Determination today leads to success tomorrow."
"There are only two ways to fail at anything that you do: Quit or don't start."
"If you're driving down the road and get a flat tire, do you fix it by slashing the other three?"
"Set small and realistic goals. 5 minutes of something good is better than 5 minutes of something bad, and better than nothing at all. Give yourself credit for even the smallest successes. It's not about starting over Monday. It's about starting over now. And it's not about being perfect or imperfect, bad or good. It's about doing your best."
"Since every failure is a lesson, every challenge an opportunity, and every joy a triumph, it's hard to go wrong."
