To know oneself, one should assert oneself.
Do not weep do not wax indignant. Understand.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
Who seeks shall find.
Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
There's always a learning curve, where you've got to learn what your subject is all about.
