We can only control our actions, but what happens around us is outside our control. The best we can do is try to influence it, but even that is limited to those within our immediate vicinity. At some point, we must learn to let go and stop trying to control something we have limited control over. I am reminded of the Buddhism teaching that we have expectations in life and when those expectations are not being met, we suffer. Simply do your best, and accept whichever outcome.
