What is this Masterclass about?

They say that you have to wait for the right opportunity to come. Yes, timing is essential to success, but you also need to realize when you need to be patient and let things fall into place and when to make it happen. If you keep waiting for the next great thing to happen in your life, then you may be waiting for a while. It’s better to do something about it.  Like what Milton Berle said, “If opportunity doesn’t knock, build a door.” Sometimes, it’s all about creating that right opportunity instead of just waiting for it to come. You can’t always rely on chance. We need to create opportunities that will lead to our goals and success.
