Life has its own signs and warnings. But it is up to us if we're dauntless enough to do the things that scare us the most.
Fear can be a good thing too. But it's not really a great move to look at fear, straight in the eyes, and allow it to consume you fully. Overcoming it is a way healthier. It's one of the most important process you can learn in life.
I'm not promoting this for you to go after and do the dangerous things. I mean, there's a thick wall that separates between overcoming fear and defying common sense. And I guess knowing the difference of the two depends on how much trust you put on yourself. It's up to you if you're brave enough to put down your bag and jump off the canyon.
P.S. Find that someone who will dare to defy fears with you.
