Hard work and perseverance will get you started and get the ball rolling but it only does so until you take the next decision. The next decision is to branch out and invest in another source of income. A millionaire has got more than seven sources of income. thus the decision to branch should be important to be successful in the long run. 

 

Every institution or business starts in the mind of a single person and then it branches out to multiple people, which becomes a big business, then it also has to split and become different businesses. People don't usually get the importance of multiple incomes and they put all their eggs in a single basket, which will make them work for their entire life. Learning to make passive forms of income is important and should be looked into to continue to be successful in life.
