Follow the goal creep
What I get out of all these different posts on motivation is that the amount of motivation matters a lot, the type of motivation matters very little, and motivation and come from very different places for different people.Some of the most successful people are highly motivated by their insecurities (eg Warren Buffett). Some have a very specific vision they want to accomplish. Some like dhh follow one goal at a time. Some simply grew up with the expectation that great things were expected of them and see their success more as a result of their habits than their goals. Some are motivated by revenge. Some are motivated by proving others wrong. Some are motivated by not wanting to be ordinary. Some are motivated by wanting to be accepted and loved. Etc.So really, the best thing you can do is look back at your own life and figure out what drove you to action. What was the time in your life when you were most productive & effective? And what was your life like then?
