Downsize your ego. Think about real needs prior to think about fame. Looking cool is fine, but it won't sell garments by itself. If you are planning to become a fashion designer, you will not only make apparel for yourself or for famous people. You can't making a living out of that: they're not even 1% of the population. Even though you see big names in magazines: it's advertisement, not the reality. It doesn't work that way. Designers are especially needed for people with real, imperfect bodies that still want to look their best. Having a snob attitude will blind you from making money. Reality is: you don't design for yourself, you design for others.
