Some decisions are easy, and some decisions are hard.
What’s the difference?
It seems that we’re predisposed to like doing some things, and we’re similarly predisposed to dislike doing some things.
When we like doing something, and it’s the right thing to do, it’s obvious that we should do it.
When we dislike doing something, and it’s something we shouldn’t be doing, then it’s obvious that we shouldn’t do it.
Where it gets hard is when the right thing is unpleasant to do (perhaps firing somebody or giving somebody negative feedback), or the wrong thing is pleasant to do (heroin, playing video games all day, etc.)
We cannot always rely on how we feel about something to make a good decision. James Clear described this in The Evolution of Anxiety: Why We Worry and What To Do About It.
