Problems are not stop signs, they are guidelines.
The secret of getting ahead is getting started.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Go for it now. The future is promised to no one.
Well done is better than well said.
To be a good loser is to learn how to win.
Know or listen to those who know.
Begin to be now what you will be hereafter.
The diversity of the phenomena of nature is so great, and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking in fresh nourishment.
