HAPPINESS is a feeling & a lesson as well. You can’t be happy with someone while being unhappy with yourself. Same applied from the other side, “never expect from yourself that you can keep others happy with you while being unhappy with yourself”, you can’t.
Either ways there is always an easy TAP-TIP for every little thing; Try to live a simple life where you don’t need to lie/hide anything. Negativity held within makes us heavier to move ahead towards life killing own clean emotions. Happiness is nothing but living a guiltless lighter life.
