I simply love typography. You can really have fun playing with fonts, designing posters and all kind of promotional materials based only on typography and in the end come up with something amazing. When you are in the logo design business, you really need to know all about typography, fonts and everything because a good symbol is bad without a good font that fits perfectly with it. Start with the basics and develop amazing skills just playing with it, there are unlimited oportunities just because there are so many beatiful created fonts out there and because you can create your own font depending on your need at the time once you developed some skill in this particular area of work. You can see examples of logo design where typography is used really good here. Have fun looking at this amazing designs:
