Go for it now. The future is promised to no one.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
Without hard work, nothing grows but weeds.

Wherever you are - be all there.
Well done is better than well said.
The secret of getting ahead is getting started.
