The actions, thoughts and words that become a permanent part of you are the ones you choose to repeat over and over again.
Doing something once will certainly bring some kind of result and doing it repeatedly will multiply its power many times over.
You cannot lift a thousand pounds all at once. Yet you can lift one pound a thousand times.
In the repetition of your thoughts and actions, there is great power. Choose to make complete and purposeful use of that power.
Add immense leverage to what you do by doing it again and again. Give great strength to your actions by persistently repeating them.
Nothing of value is ever accomplished in an instant. No skill is ever fully developed in a single day.
Take the time to make the effort over and over again. That time and those efforts will bring great rewards.
