Here are a few I liked:
Don't allow anything in your life that you don't want reproduced in your
children's lives.
Don't ask the question, unless you really want to know to truth.
Don't be a hard rock when you really are a gem.
Don't be afraid of trying something different. It might be fun!
Don't compromise yourself. You're all you have.
Don't do anything that would make your enemies happy.
Don't do whatever you like. Like whatever you do.
Don't ever let yesterday's disappointments overshadow tomorrow's dreams.
Don't fear your abilities. Fear your mind. That's what gets in the way
of success.
Don't fix something that is not broken.
Don't fly any higher than you're willing to fall!
Don't follow where the path may lead. Go instead, where there is no path
and leave a trail.
Don't forget what you did yesterday. It made you who you are today.
Don't forget, when you meet strangers or friends, some are angels unaware!
Don't frown. You never know who might be falling in love with your smile!
Don't have the best of everything. Make the best of everything you have.
Don't let a past of hurt keep you from a future of love!
Don't let life pass by without noticing it's there!
Don't let others spoil your happiness.
Don't let the devil ride, because he'll want to drive!
Don't let what you can't do interfere with what you can.
Don't piss me off. I'm running out of places to hide the bodies!
Don't quit five minutes before the miracle!
Don't run faster than your Guardian Angel can fly.
Don't say it if you don't mean it.
Don't take those who you love for granted, because when you wake up the
next morning they just might not be there.
Don't walk before me. I may not follow. Don't walk behind me. I may not
Lead. Just walk by my side, and be my friend.
