If you're going through hell, keep going.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
By failing to prepare, you are preparing to fail.
The secret of getting ahead is getting started.
Go for it now. The future is promised to no one.
Know or listen to those who know.
If you can dream it, you can do it.
If you've got a talent, protect it.
You never know what motivates you.
It's amazing that something only an atom thick can be an impenetrable barrier. You can have gas on one side and vacuum or liquid on the other, and with a wall only one atom thick, nothing would go through it.
