I know the prospect may sound daunting. After all, there is no shortcut to mastery or greatness. And if you spent your life as an introvert, your communication skills may be very deficient. You may have encountered obstacles, failures and fears and ended up believing that success is really not for you.
True, self development is not something that happens overnight.
It may take a lifetime to master some things but if you are aware of your powerful potential and your creative capacities, you will be amazed at how much difference it can make in your life.
Just as "in one drop of water are found all the secrets of all the oceans", all you need to do is open your eyes to see your flexibility, courage, innovative spirit and highly creative nature in order to evolve from "not knowing what to do" to having a crystal clear path towards mastery of your social skills.
