Spread the positive vibes.
Give goodness to others.
While all of that may hold true, if you’re an introvert, none of this might hold true to you.
You may just want to sit around and observe life. Be calm and say nothing. Simply smile with an acute gratitude and bliss at the same time. Forming stories inside your own head.
Just be that, the world needs your things, as Susan Cain said. You being yourself is the best gift you could give to yourself.
