Dr. Andre Marques-Smith explains the absolute necessity of engaging with your passion throughout life: staying focused on the things that nourish your passion, noticing when your passion starts to wane and when it does, assessing the situation and making decisions that will open up new paths of passion once again. He talks about his changing interests over the course of his life and how he has easily let go of old habits in order to embrace new and emerging interests. Dr. Marques-Smith argues that we will achieve only mediocrity if we stay in a place after our passion dissipates and that moving on is essential despite fears and sunken costs.
