To know oneself, one should assert oneself.
If you're going through hell, keep going.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
Either you run the day or the day runs you.
You never know what motivates you.
Always desire to learn something useful.
Problems are not stop signs, they are guidelines.
Begin to be now what you will be hereafter.
If global cooling will come soon - scientists will lose trust.
