As hilarious as it sounds, its the simple truth of life. If opportunity does not call then build a door. You build a door when you do what will attract the opportunity to come.
Start somewhere, you have a dream, a vision or an aspiration, start now, do something about it. What you need to do could be as simple as creating and short and long term goals based on the aspiration and mapping out active steps to follow. Don’t think of a greener pasture across the fence or wait for when opportunity will be better, start here and now, start where you are with what you have.
