Always desire to learn something useful.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
Either you run the day or the day runs you.
Begin to be now what you will be hereafter.
If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
Well done is better than well said.
I learned easily and had time to follow my inclination for sports (light athletics and skiing) and chemistry, which I taught myself by reading all textbooks I could get.
