External confidence is what you project to others. It can be faked. Internal confidence is the security you receive from years of introspection and self improvement. External confidence can get you through a moment, but internal confidence can get you through life. It comes from honing your core skills and having repeated success.
Confidence comes not from controlling the perception of others, but in projecting the truth of who you are. When you unapologetically embrace your unique characteristics, people respect you more. There are 7.5 billion people on the planet, connect with those that share your passion.
Don’t follow the false wisdom of setting “BIG” goals. Rather, have “BIG” dreams and ambitions, but structure a plan that incorporates stair-stepping, achievable goals. This will build your confidence along the way.
