You have a dream.
So, just like every single one of us, you ask, “Do I have what it takes?”
The answer is yes. Every other answer is a lie, an excuse or a distraction. The call itself is enough of an answer.
I consider myself good at a few things, passable at many, and passionate about more. What I’m capable of is completely irrelevant. I’m likely the worst to judge that anyway.
You prove yourself “capable” by simply doing.
