The test of how far your wisdom has matured lies in the strategic skill with which you can keep yourself from doing things that you like to do but that would cause long-term harm, and the skill with which you can talk yourself into doing things that you don’t like to do but that would lead to long-term well-being and happiness. In other words, mature wisdom requires a mature ego.
- Thanissaro Bhikkhu, “Hang On to Your Ego”
