If you think you can do it, you can.
You never know what motivates you.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Know or listen to those who know.
It's always too early to quit.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
Well done is better than well said.
Problems are not stop signs, they are guidelines.
Life is a series of steps. Things are done gradually. Once in a while there is a giant step, but most of the time we are taking small, seemingly insignificant steps on the stairway of life.
