TIP 1 Keep it Simple!
A complicated logo will not only make your logo difficult to reproduce and maintain, but you will also fail to engage your audience. You don't have time to recite your entire business plan in an elevator pitch, and the same concept applies to corporate logo design.
Often times, it's better to start over with a new concept or remove distracting elements rather than add them.
Simplicity isn't always an easy thing to achieve, as you don't want your logo to appear too boring or conservative. This is why at the end of the day it's best to leave it to the design professionals!
