The issue is not that you do not have as much energy as successful people. You do. With few exceptions, we all have energy. It is just that you invest your energy in hate and resentment instead of on love and contentment. That is the difference between you and joyful people. You cannot plan your success. But the minute someone offends you, you can plot your revenge with laser focus. When was the last time you rewarded or appreciated someone who helped you? But you can easily remember the last time you dealt with someone who slighted you.
