When a person finds themselves in a job role they don’t want to be in, it often takes a while to leave.
They may regularly have the thought that of handing in their resignation, being in a job where they feel valued or starting over in a new city. However, they don’t take these thoughts seriously enough for them to result in taking action. Instead they consider them to be like a sort of daydream.
And this can go on for months or even years until they finally decide that they’ve truly had enough.
Or sometimes they’re pushed by unfortunate circumstances.
I guess the point is that if you’re unhappy and you know exactly what the cause is then you should do something about it. Happiness is possible, it doesn’t just have to be something that you daydream about.
