Everyone has that ability to succeed and in this life, will be offered the oppurtunity to do so but not all will. I will give some reasons why some do and some don't below:

-Have or build the right mindset. Your environment(friends,books,media,location etc) influences your mind. They affect what goes in and therefore what comes out.

-Stay away from negators, pessimists, procrastinators and vision killers.

-Hang out with big thinkers, optimists and vision builders.

-Dress, think, talk and feel important. You attract respect when you look sharp, intelligent and dependable. You will also notice, you perform better when you are better dressed. It is a psychological thing.

-Never belittle yourself. Believe you can achieve anything and you will be able to. Daily recite words that make you feel more self confident and less afraid and your mind will start to see more possibilites than limitations.

-Use time wisely. Set goals then work tiredlessly towards achieving them.
