To know oneself, one should assert oneself.

Know or listen to those who know.

The most effective way to do it, is to do it.

If you think you can do it, you can.

What you do today can improve all your tomorrows.

It's always too early to quit.

Be kind whenever possible. It is always possible.

Without hard work, nothing grows but weeds.

You never know what motivates you.
