Mistakes are merely steps up the ladder.
You never work for someone else. The truth is someone is paying you to work for yourself.
Productivity is never an accident. It is always the result of a commitment to excellence, intelligent planning, and focused effort.
Success is the progressive realization of predetermined, worthwhile, personal goals.
Enthusiasm is the yeast that raises the dough.
If you are not making the progress that you would like to make and are capable of making, it is simply because your goals are not clearly defined.
