Who seeks shall find.
To know oneself, one should assert oneself.
Go for it now. The future is promised to no one.
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.
Do not weep do not wax indignant. Understand.
After a storm comes a calm.
I can, therefore I am.
Never complain and never explain.
In hard-core science fiction in which characters are responding to a change in environment, caused by nature or the universe or technology, what readers want to see is how people cope, and so the character are present to cope, or fail to cope.
