Suspend Judgement
This is life. In the middle of things, it can be impossible to know what is good or bad and whether to be happy or crushed by your circumstances. What remember in order to counter our tendency towards misjudgments and emotional whiplash is that our job is to deal with life as it comes. The time will come for judgment to be passed on the things that happen in our lives, but until we get there, its best to suspend judgment and deal with whatever we are facing as calmly as we can manage.
