Be kind whenever possible. It is always possible.
Without hard work, nothing grows but weeds.
You never know what motivates you.
By failing to prepare, you are preparing to fail.
I can, therefore I am.
After a storm comes a calm.
Always desire to learn something useful.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
Never complain and never explain.
