Well done is better than well said.
It's always too early to quit.
Know or listen to those who know.
The most effective way to do it, is to do it.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
Only the educated are free.
Who seeks shall find.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
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.
