Guy Kawasaki...

Guy Kawasaki is a managing director of a venture capital firm in the US.

(read more here...)

He has a video on Google that shows his presentation about his book "The Art of the Start". I think it is a very refreshing look on starting up a business and deserves to be seen, not just if you want to start up a business, but also if you want to revive your own work and re-evaluate your contributions to your company (how it can be made more effective).

Check it out, and then perhaps buy his book :)
