Problems are not stop signs, they are guidelines.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
Well done is better than well said.
It's always too early to quit.
Begin to be now what you will be hereafter.
What you do today can improve all your tomorrows.
One of the nice things about science fiction is that it lets us carry out thought experiments.
Some ideas you have to chew on, then roll them around a lot, play with them before you can turn them into funky science fiction.
