is studying important ??? or we just need luck to be succesful....???

I believe studying and luck need to go hand in hand. You'd need to know the necessary skills you get from studying for the duration until you finally luck out, say by creating a product that sells unexpectedly high. As well, you'd need skills even after you luck out--taking the previous example, you'd still need the management and marketing skills that you learn from a management course to maintain and possibly expand your business for a higher profit.

All the great persons are the persons who worked hard and there was a time that i use to think like the way that you are thinking right now. If we don't work hard then there is less chance for the luck to come our way. If we work hard than we will surely be somebody, If you are studying than give your full interest in your books one day you will achieve something.

You only see those people on TV becuase they are so lucky. The people that study and work hard generally get rich but becuase it is not down to luck they just live quieter lives and dont get much notice.
