It's always too early to quit.
Problems are not stop signs, they are guidelines.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Do not weep do not wax indignant. Understand.
The trick with computers I think, is to approach old and new things with the same reverence as you would like your favourite chair and not be seduced by the constant innovation otherwise you never do anything.
