That thing you're carrying, how much does it weigh?
Does it slow you down? Tire you out?
Does it give you blisters? Have a pointy edge?
Do special tools help you bear its load?
Our situation often seems heavy, but what does it really weigh? Why is it that sometimes trying to prepare Tuesday night dinner can be just enough to put us over the edge? Why is it that one email, one comment, one argument, one more to-do, can be too much to bear?
We bump into these things all the time. Little things, insignificant ninnyhammers, that put us over the edge.
Weight is relative. It depends on relations and circumstances, attitude and approach. Next time you're feeling the grind, take a look at how you are carrying the load.
