Never get INTIMIDATED by BIG BUSINESS, if you do you can never succeed. The desire to succeed and invent new/improve solutions made a Larry Page, made a Sergey Brin and made a Mark Zuckerberg and numerous others and we will see many more in future.
How ever small you are, know what's going on around improvise, build upon, create new and give it a go. Overtime if you earn your bread, living a good life and doing just what you want to do then YOU ARE ALREADY SUCCESSFUL. Need not be as rich as the Stars I mentioned above, but you are still doing GOOD!
So again lot of it depends on what you are aiming to do!
