Quoted By:
Nearly everything is bad in excess. Too much desire can drive people to suicide if those desires aren't met. Just stop desiring in excess. Keep your desires as mild motivators, but never become so attached to them as to go down with them should they fall. Be prepared to shed your desires if they start to bring you down. Sure, some have become very successful from focusing on their desires to the point of madness, but I'm willing to bet that far more have committed suicide due to the desires that enthrall them.
Get some sun. Fast for a week. Randomly exercise. Clean your home. Practice a martial art. Read anything that seems interesting. Do simple things. Stop focusing on desires that take too much without immediate reward. Let them be background to the desires that give you something. If it is to be, then the long term desires will come. If not, let them go.
