If you think you can do it, you can.
You never know what motivates you.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
Go for it now. The future is promised to no one.
What you do today can improve all your tomorrows.
It's always too early to quit.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
There is even a happiness - that makes the heart afraid.
Some minds improve by travel, others, rather, resemble copper wire, or brass, which get the narrower by going farther.
