"Most of the best decisions in my life came after I realized I don't know everything ... the more something feels like something you don't need to know, the better the chances are that it's something you could really benefit from."

— Merlin Mann on The Pipeline

I heard this interview with Merlin Mann recently and his thoughts on curiosity were right on. I haven't experienced enough success in my own mind to start dishing out advice, but I think if successful people have one thing in common it is perpetual curiosity. They explore things they are interested in for the simple sake of learning; not because there's something in it for them. In many cases, their curiosity ends up having a profound impact on their life and/or their business.

Merlin Mann's interest in productivity eventually made him one of the first full-time bloggers on the internet and a very highly-respected geek in many circles. Gary Vaynerchuk's interest in wine made him one of the first and still one of the most successful video bloggers around.

Fact is, you never know where your curiosity will take you. It could mean a new product idea, a new philosophy, a new job or just a new hobby in the long run. The end game frankly doesn't matter. Just never stop learning, because it could be the start of something great down the line.
