It seems to me that a lot of people have distorted views of drive and intensity. People seem to think they need to work 90 hours a week exclusively on one thing in order to be a success. They hear stories all the amazing things that startups accomplish or this or that great hacker have done, but get the timelines all wrong; thinking they accomplished it in days or weeks.

I came up with this definition for myself over on another thread

Drive and Intensity to me means frequently (daily or bi-daily for fitness) making small amounts of progress on your goals.

Intensity without drive. Working on something for 8 hours then forgetting about it for a week or more.

Drive without Intensity. Working on your project all the time, but never getting anywhere with it. (Always in planning/research, making it perfect, etc)
