I think about this in yogic terms. In the niyama of yoga there are two guiding ideas that – at first – seem contradictory. Santosha is contentment. Tapas is discipline. So, on one hand, Patanjali was suggesting one needs to accept what one is (santosha,) but, on the other hand, he was suggesting that one needs to keep the fire of self-development burning (tapas.) [Note: I realize there are different readings of these two concepts, these are the versions that have resonated with me.]
These two ideas did seem at odds until I realized that they answer different questions. Contentment is the answer to “Am I enough?” Tapas is the answer to “Can I be better?”
Long story short, I see wishes such as the desire to be six inches taller or to be a celebrity as a waste of time and mental energy. However, I see the need to be a healthier and more equanimous version of myself as an ever-present driver.
