Obsession OR Passion ~
There's good obsessions and bad obsessions. Healthy obsessions are goal oriented, with praticality, and a deep understanding of purpose. It's not flagrant. Obsession without wisdom will use you. It will direct you to distraction. Obsession with wisdom is passion. It will serve you.
Obsession can be seen as passion, and at it's worst, addiction. Passion can be hard to control, but without passion, there is probably no precedented growth, regardless of the vocation. Obsession can harm you, especially if you haven't dealt with your past properly, and your imprinting is affecting the trajectory. What framework are you building in your life by being obsessed with the things you choose? If you love something, or someone, there's a form of obsession included. It's up to you to create HEALTHY dynamics to reach your goals. It's good to be obsessed with health, until it's harming you. It's the same with relationships. Same with work. If your obsessions are hurting yourself or others around you, it's probably controlling you. Obsession is good...unless it's ruling you.
Now go and be great ~ .
