If you have to work with or deal with someone you don’t like, you know how to deal with that? Stop reminding yourself what you don’t like about them. Focus on the work before you. Focus on any of a thousand other things available to focus on in the moment, and your ego will get over it soon enough. Ask for guidance to see that situation and that person differently, and to be open to whatever might be learned from them.  When I must be around someone I have resistance to, I’m thankful for the trigger and the reminder that I have emotional work to do. I meditate on the degree of my irked-ness and ask myself the ever deepening question: what is it about this person that makes me give them so much power over me that it changes my mood? Then I listen intently and see what answer unfolds.
