If you're going through hell, keep going.
It's always too early to quit.
Leap, and the net will appear.
After a storm comes a calm.
Well done is better than well said.
Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
I found out that colonels can stay until they drop dead or get a walker and being a critical medical specialty as an Army trained emergency room doctor, I could stay until age 67.
