The problem is not that people will stop relying on you because you rarely deliver on your promises.
The problem is not that your productivity is going to decrease because you are juggling too many things.
The problem is not that your dear ones will no longer seek out your company and your help because you are never truly there.
When you do not put boundaries, when you equate busyness with status, when you take the shortcut of being on top of it all, the real problem is that you have lost sight of what is important to you.
And if you have lost that, how are you going to achieve it?
