Nobody wants to get rescued by an ambulance with a flat tire.
As noble as it may seem to address everyone’s problems, the first person on your “to-do list” should be…you. Taking care of yourself is taking care of others. The fewer problems you have, the more you become a beacon guiding others away from theirs. So tune up your ambulance before trying any more daring rescues! Remember, to be selfish is to be selfless.
