As @Jayster pointed out, “live with a little ambivalence.” The pros have been saying for years that the ability to live with ambiguity and conflict is the highest state one can reach in life. It’s definitely what the Buddhists and Sufis are seeking in their Vipassana meditation practices.
There are plenty of books – and workbooks – to help one acquire this capacity. I’ll list a few here:
