Be gentle to all and stern with yourself.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
Quality is not an act, it is a habit.
Begin to be now what you will be hereafter.
The dog that trots about finds a bone.
Well done is better than well said.
It's always too early to quit.
Either you run the day or the day runs you.
If you're going through hell, keep going.
I like to browse in occult bookshops if for no other reason than to refresh my commitment to science.
