Fear is a signal. It's your brain trying to warn you. But that signal is unclear.
There are two types of fear: silly and serious.
Silly fear is concerned with rejection. If you looked at yourself from afar, you'd say: "what are you waiting for?"
Serious fear is concerned with consequences. If you looked at yourself from afar, you'd say: "What are you doing? Pause."
Silly fear is the hesitation when sending an email to a stranger.
Serious fear is investing in a convenience store without a business plan.
Silly fear is posting your work in public.
Serious fear is quitting your job without another way to support yourself.
Silly fear is a sign you're exploring new things.
Serious fear is a sign you need to pause and reflect.
In both cases, fear must be respected and explored. Don't ignore your fear.
