Yeah, you really just need a pencil and alot of paper. Formal education will give you some credibility, but it’s more for networking. That’s why I think if you are going to choose a program, choose one with alumns you respect and would like to work with. Everybody says it doesn’t matter, but I’ve seen from experience that sometimes what school you went to matters and is a bonus. I went to a regular public school and have been looked down upon by alot of Alumns from, EHEM! STANFORD. Damn you IDEO. lol.
