Quality is not an act, it is a habit.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
Begin to be now what you will be hereafter.
If you can dream it, you can do it.
Well done is better than well said.
Be gentle to all and stern with yourself.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
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.
