You must “use them” instead of having them use you! Emotions can make you stay up all night to build on a dream or have it turn into a nightmare. They can give you the energy to lift that extra pound or pick up that deadly weapon. That is why emotions must be under your tight control utilized for the purpose of making you successful and happy over the long term. Try not to release them in situations where another smells victory. You don’t have to keep them locked up in a box but understand when and where are the best places to use them for your benefit . Concerts, training, movies, art etc are where your expressions can fully come to life. Yes, it’s not nice to use others but with emotions try and make the exception then you’ll see how high they can take you.
