To be successful, you have to work harder and smarter than everyone else. That's what I used to think. I couldn't be more wrong. I came to realize the most successful people, in terms of impact, are the ones who can work harder and smarter with everyone. It's always about team play, there is no such thing as a self-made man/woman.
A corollary of this statement is the need to be engaged in communities to find people you can learn with and make progress.
Similarly, a great tech product helps you work harder and smarter with everyone: community is both the pillar and the vector of growth (cf @jasonleow 's post about Naval's approach to define an effective business model).
I've never been consciously aware of it up until now, and that's one thing I need to work on with 200 Words a Day. Most people here work for themselves, it's more about personal growth than community growth. There are interactions, and close friendships have been made, but it's not as flourishing as it should be. How can we truly write together? Maybe it's time to have our first community event.
