No doubt there are limiting factors and risks in anything that you do, but I'd rather find those by bumping into them, not by cautiousness. I'd rather get a new paint job and win the race than lose without a scratch.
BTW, not sure what you meant actually, but it just brought out the thought.
It's like going to get a PhD without researching what that makes your life like, etc, just because you like ______ topic.
"Should I be an entrepreneur" is a good question to ask oneself before being one. It shows measured caution, which is evaluation of oneself before embarking on something. The mark of a successful entrepreneur is taking measured risks, not silly risks. Those who take silly risks are just accidental winners if they win.
The unwillingness to figure out if you'd be good at something before jumping in with both feet is a great way to show where you are on the spectrum of the Dunning–Kruger effect.
Funny, because that's exactly why I got mine. :) -It's worked out fine.
I think there should be an antithesis to the Dunning–Kruger effect: exceptionally-intelligent people don't achieve their potential, because their ability to see all possible roadblocks kills their confidence.
Bertrand Russel put it more succinctly: "The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt."
Sometimes you have to dare to be stupid. :)
People shouldn't clamor for fog on the mountains they're going to climb to not get discouraged. They should develop enough self control to accept a challenge with eyes open. Then they know where they're stepping and can plan, as the mountain is in view, instead of shrouded in fog.
I mean, do you do brain research in a startup? I know I've been in my business for 4 years here after taking measured steps for years before that and it worked out fine.
