If it ain’t broke, don’t fix it.
A common phrase that essentially means, if something is going well don’t change it.
We don’t have to wait until something is broken before we decide to fix it or change it. You could be in the habit of doing something like eating chocolate chip pancakes everyday for breakfast. You never miss a day and always make time to sit and relax whilst you eat.
Essentially, nothing is broken.
But you might be better off eating fruit, or oats instead.
Just because something isn’t going badly, doesn’t mean it isn’t worth thinking of how you can make it better.
