Adrenaline is good.
You have to do things that scare you every now and again, they remind you of what it means to feel alive.
Life isn’t linear, and we, as people, aren’t rational - sometimes you simply have to trust whatever the hell happens next. In the words of the great Carl Gustav Jung -
“That which you most need will be found where you least want to look.”
So, go and do something that scares you, it might just be the very thing you need.
