The secret of getting ahead is getting started.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
Go for it now. The future is promised to no one.
Do not weep do not wax indignant. Understand.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
Always desire to learn something useful.
But I don't think we'll go there until we go back to the moon and develop a technology base for living and working and transporting ourselves through space.
