Doesn’t everyone say opportunities knock only once? I used to agree to that phrase too, until today. Opportunities can knock twice and they can knock the air out of you for the second time! 😛
Also, it is not always that the opportunities will knock at your door. Sometimes, you’ve to make the door and leave it slightly open to let the opportunity in. And once it puts one step inside the door, just catch it’s leg and drag it in. Don’t let it leave from the door. Otherwise, building the door will be totally worthless.
So, if the opportunity knocks, open it. Or invite it by making a door. Or just pray that you’re lucky that the opportunity knocks for the second time! 😉
