If you think you can do it, you can.
If you're going through hell, keep going.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
Know or listen to those who know.
Without hard work, nothing grows but weeds.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
The most effective way to do it, is to do it.
You never know what motivates you.
There is nothing deep down inside us except what we have put there ourselves.
