If you're going through hell, keep going.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
You never know what motivates you.
Either you run the day or the day runs you.
Know or listen to those who know.
The most effective way to do it, is to do it.
If you think you can do it, you can.
The best museums and museum exhibits about science or technology give you the feeling that, hey, this is interesting, but maybe I could do something here, too.
