I think negative energy all due to the reason that you can not be yourself you can not act as what you think and you lose the freedom. loyal to yourself is an ablity it also need many couragements.although  it needs many couragements but once you get the couragement and begin to listen to your heart but not listen to the world then you will become more and more free and get more and more positive energy. life will never have a fixed pattern all the social convention is not that important, the most important is what you really want in your inner mind. so the best positive energy is to do yourself, listen to your heart act as what you want .
