You can. You distance yourself from people, suggesting yourself over and over that you don't really need much social interaction, communicate with people only outside perceptions and feelings and the entire world around you starts to change. Each time you'll catch yourself analyzing emotions you'll stop due to its error-prone nature and switch to analyzing facts and social mechanics. There are of course many other things but this should do for a start.
My belief is that emotions were a capability developed in social creatures to cope with social intricacies given the limited rational capabilities. Emotional behavior is a kind of mechanisms to produce simplified response out of vast amounts of information that had to be processed fast (and not necessarily in great detail). Things changed a lot since then and nowadays the game-of-life competition includes a lot of gimmickry which relies heavily on exploiting emotions¹! The said autistic nature may be as well the direction in which the entire humanity is heading to.
