If you want to be successful, you can start at anytime. But you must start.
Don't make the mistake of not doing anything because you can only do a little. Do what you can do.
It will always be your attitude at the beginning of any difficult task which, more than anything else, will affect its successful outcome.
To be aware of what you want and not go after it, to spend years wondering if something could have materialized, and never knowing if it could have been, is a tragic waste of your life. The worst thing you can do is not to try.
To reach a port, you must sail. You must sail, not lie at anchor. You must sail off in the direction of your dreams, not drift.
