This is very true. Another negative about being jelousy or making bad judgments about people is because then you are potential judging your future self. Are minds do not see separation and much as we consciously think we do, therefore are subconscious judge the conditions more than the actual person.

When we make a negative judgment against a successful person (rich, famous, talented, etc.) we are doing one of two things:
1 If we do become "successful", then we must personally face our own judgment and hypocritical aspects of ourselves that we cast off onto others for having the same experience.
Or
2 If we do not become "successful", then our judgments toward those who are very well could be part of the cause of that; It's take a lot of energy to resist oneself. Embrace & support that which we want to see within ourselves. Then when we star to become that we have the best type of support a person can have their self

Find the gift that you passionately want to share with your fellow man and that is when/how we , as humans,will expand the most.
