Finishing your studies is not the key to achieving success in life.
I agree but it is a common ticket to become successful in a career.
It is just the first step that you need to build yourself and help you prepare for the obstacles that may come to your life.
This is it. Those that are starters, this is where they can start with and capitalize the diploma and the studies that they've done over long the years that they've dedicated learning. It's a way but it might not guarantee a person's success but at least, it won't be taken away from you.
It's one of the weapons you can use to fight with the reality in life. Now, once you graduate, it is up to you how you can nourish the things you have learned to improve yourself and become a better person who can bring you success and wealth. Some still fail even after achieving and learning a lot in life, but the key to managing on continuing the journey to be successful and wealthy is to never give up and continue to try again.
As someone graduates, the life that he's going to work on depends on how good he is and strategic you are as a person. With or without studies, someone can be successful and people might say life is unfair, which can be true sometimes but this is one good comparison of it to say that life is fair.
