Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
Leap, and the net will appear.
You never know what motivates you.
Either you run the day or the day runs you.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
Go for it now. The future is promised to no one.
I can, therefore I am.
If you're going through hell, keep going.
Failure and things of this sort - you can take it one of two ways. You can either let that hurt you and really affect the way that you live your life in the future, or you can use that as an opportunity for growth.
