I go about it in a bit of a round-about way. I'm a pretty introverted guy, so I make a point to work on soft skills like communication or public speaking to do demos. I've found that by getting out in front of others, they'll inevitably have questions for you, some of which you can't answer. If you let them know you'll get back to them with the answer, you become the "go to" person and you have someone else find an area you can improve on. The more you do this, the more you'll learn and eventually everything kind of falls into place.
