Building up awkwardness resistance

There's a whole bunch of situations that make me cringe inside. Not in the slight nervousness kind of way, that would be good, usually a sign that the thing you're nervous about is exactly what you should be doing.

In this case, I mean just a feeling of "I don't want to be here, make it stop". Examples include cologne stores, clubs or cafes by myself,...

Lately I've been putting myself in these kind of situations, just to get used to dealing with and successfully ignoring awkward feelings. Plus, I get really creative in finding stuff do to, finding reasons to talk to people etc, just to get out of it.
