If you’re used to always being the one to bend to the needs of another, you might reach a point where you decide to change. Perhaps after an epiphany about the importance of balance.
When it comes to some change, the advice is to go slow and take it bit by bit. However, when it comes to changing a habit of compromising, it’s probably more helpful to go cold turkey.
The reason for this is that no compromise allows you to gain clarity on exactly what you want to do for yourself without taking others into account.
It’s then from a place of clarity of your own needs that you can learn to compromise properly.
