Problems are not stop signs, they are guidelines.
It's always too early to quit.
The most effective way to do it, is to do it.
By failing to prepare, you are preparing to fail.
Wherever you are - be all there.
After a storm comes a calm.
You never know what motivates you.
Always desire to learn something useful.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
To see what is right and not to do it is want of courage, or of principle.
To know what you know and what you do not know, that is true knowledge.
