Go for it now. The future is promised to no one.

Be gentle to all and stern with yourself.

It's always too early to quit.

If you think you can do it, you can.

Always desire to learn something useful.

The wise does at once what the fool does at last.

Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

Know or listen to those who know.
