By failing to prepare, you are preparing to fail.
After a storm comes a calm.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
It's always too early to quit.
If you think you can do it, you can.
Go for it now. The future is promised to no one.
Leap, and the net will appear.
The most effective way to do it, is to do it.
Begin to be now what you will be hereafter.
I think that somebody with the resources and innovation and the idea is going to come out of nowhere and come up with a successful space travel program.
