Don’t confuse courage with impulsiveness.
Being fearless means not much when it doesn’t come from fear first. Any breakthrough will only matter, if it’s made both mental and emotional.

Thinking things through is as important as following your heart. Because in your soul, the two combine. Cognition plus emotion form what you consider as self. All ego aside, you will need that self to be who you are and become who you want to be. There is no moment when you’ll have any of these figured out. It’s an continuous proces, we like to call it life. And it’s clearly not about getting somewhere, but it is about going.
