The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
After a storm comes a calm.
Expect problems and eat them for breakfast.
Well done is better than well said.
If you're going through hell, keep going.
It's always too early to quit.
To know oneself, one should assert oneself.
If you can dream it, you can do it.
Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
