The house of success is built brick by brick. You can do what you want to do, achieve what you want to achieve, and attain any reasonable objective you may have in mind. Not all of a sudden, not in one sweeping act of achievement. You will do it gradually, day by day. If you want to do it, if you work to do it, you will accomplish your goal over a sufficient period of time.
Maximum success is achieved in steps.
Your big accomplishments will be a series of little accomplishments. It takes many strokes to overthrow the tallest oak. Reality forms around your commitment. The achievement of your goal is assured the moment you commit yourself to it. Learn that obstacles don't matter very much.
