Technological phenomena

What do Apple, HP, Google, and Microsoft have in common? If you guess they're all computers, aside from being captain obvious, You're correct. BUT! The answer I was looking for is that they all started in a garage. Think about it, a massive company, formed in a garage, less than 200 square feet of space. Thats pretty amazing. If something like apple can start somewhere humble and small, who's to say that someone who starts in a bad neighborhood can't become successful. No one, everyone should try there best and strive for greatness.
