Success in any area of life never happens in a complete vacuum. Often it is just as much dependent on an individual’s environment, relationships, and outside circumstances as it is on their will-power, discipline, and intelligence.
To find happiness and success, you therefore need to pay attention and take some control over the type of environments you are surrounding yourself in on a daily basis; even the strongest and brightest of minds will find it difficult to achieve their goals if they are in a completely wrong environment for them.
This is because every aspect of your external life has some influence over your internal thoughts and behaviors, especially the people you surround yourself with on a daily basis, and the type of places where you spend most of your time.
