If you can dream it, you can do it.
If you're going through hell, keep going.
If you think you can do it, you can.
Well done is better than well said.
Always desire to learn something useful.
You never know what motivates you.
I can, therefore I am.
To know oneself, one should assert oneself.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
A sense of duty is useful in work but offensive in personal relations. People wish to be liked, not to be endured with patient resignation.
