Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
If the highest things are unknowable, then the highest capacity or virtue of man cannot be theoretical wisdom.
