When we do things for fame and power driven by ego, we seldom fulfill our deeper needs. Ego is never satisfied. The more it gets, the more it wants!
If you just do things for others and forget yourself, you end up being imbalanced and find it hard to sustain success.
However, if you do things to create a positive impact to others and yourself, you have a balanced and sustained satisfaction.
Some people have an either/or approach. They feel if you want success you cannot have balance. What they are missing is that balance creates a deeper and sustained sense of success. The more your body is healthy, the more it impacts your mind and soul. The more your mind is active, it impacts the body and the soul. The more the soul is nourished, it impacts the body and the mind.
