Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
You never know what motivates you.
Well done is better than well said.
Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Either you run the day or the day runs you.
Things do not happen. Things are made to happen.
After a storm comes a calm.
