Thanks for linking that video, I watched it a long time ago and was really happy to be able to re-watch it again. I wouldn't be able to work from home, I'd need a lot of motivation and prioritization to be able to get anything done, it's just awesome you're so in control of everything and chilled out about it.
It does take a lot of discipline, but I wouldn't say I'm "chilled out" about it. I feel a tremendous amount of pressure most of the time to "perform" in my job. I'm in business development and therefore have numbers I have to "meet" annually. If I don't my take home is literally 1/3 of what it would be otherwise. Chill? Not exactly, but I do like not having to go to an office. I suppose I succeed because I always feel a quiet pressure and the more I "chill" the louder it gets.
