Lots, but for I'd go for Patrick McKenzie for someone I could realistically emulate. Because 1) He hasn't achieved the oh-my-god millions and millions kind of success, but something more realistic and reachable, 2) He's constantly trying to help everyone else to do it, too, and 3) He is continuing to build upon his earlier success and continues to improve. Oh, and 4) He's doing it on time constraints similar to my own. Thanks, Patrick--I hope to follow in your footsteps.
Totally agree. His resume is pretty tough to beat, Apple, NeXT, and Pixar. I'd also argue that he has almost single handedly brought design to the forefront of the computer industry. Overall, a tough businessman who you can't help but like.
