To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
Problems are not stop signs, they are guidelines.
By failing to prepare, you are preparing to fail.
Do not weep do not wax indignant. Understand.
If you think you can do it, you can.
Well done is better than well said.
Quality is not an act, it is a habit.
If you're going through hell, keep going.
Leap, and the net will appear.
Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
