What is fear telling you?

Fear is an unpleasant emotion caused by the threat of danger, pain or harm.
Fear is essential because it protects us from danger. However, most of our fear is not accurate.
Fear is one of the most substantial layers of illusion.

How can we overcome fear?

Using just thinking to confront fears is not an authentic experience. Because just thinking is just a simulation of Life.
Most plans are perfect in our minds, but when we try to achieve them, they don't endure the test of reality. Similarly, when we use thinking to overcome fear. Fear pushes you to confuse what you imagine with what is real. Fear spreads everywhere.

You can feel the fear, but don't allow being imprisoned by fear. As long as you live in fear, the word is a threat. But living that way, you will never know the joy of your soul or accomplish a meaningful life.
The best way to deal with fear is to face them; then, you will overcome them. "Act while you feel fear rather than waiting until you feel unafraid." - David Richo, How to Be An Adult. The world's top performers act while they are afraid.
So don't wait until the fear is gone. Instead, work while you feel it.
It is challenging; however, you can face them in small steps and with slight progression. You see the truth when you aren't living in fear. It becomes obvious. Your time on this planet is very brief. It shouldn't be lived in fear.

Best Wishes, my friend.
