The first thing you must know before anything else applies: Truth demands chutzpah.
If what you are doing is the right thing to do, there will be others who will ridicule, taunt and attempt in every way to intimidate you. That is the way the world works.
If you can’t handle it, if you can’t ignore them as you would ignore flies on a camping trip, don’t imagine you can take a single step forward.
Only once you’ve passed the chutzpah test, only then can you begin to grow.
