Stay Low
You cannot put on a high profile and expect to learn anything from those around you. In order to learn, you must present a low profile.
Same as with water, knowledge travels from high elevations to low elevations. If you stay lower than those around you or act as if you were lower than them knowledge wise, you will have a chance to learn a lot from them. Conversely, if you give an air of a higher level of knowledge to those around you you will learn little or nothing at all from them.
