It's always too early to quit.
After a storm comes a calm.
The wise does at once what the fool does at last.
You never know what motivates you.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
Be gentle to all and stern with yourself.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
If you think you can do it, you can.
