Without hard work, nothing grows but weeds.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
Do not weep do not wax indignant. Understand.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Wherever you are - be all there.
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.
