“Opportunity is missed by most people because it is dressed in overalls and looks like work.” Thomas Edison said that.
The other expression I like is, “It’s a funny thing, the harder I work, the luckier I get.”
Working hard is the best way to put yourself in position to take advantages of opportunities, or to find yourself in a lucky situation. There’s no substitute for hard work. There are no short cuts to success. Don’t look for opportunities to take advantage of. Do the work, don’t expect it to be easy, and opportunities will find you.
