Being clear on what you can and can’t do is so important.
Imagine having a friend who’s car breaks down. They call you for help and you offer to fix their engine.
But wait, you’re not a mechanic.
You go over, pop the hood up. Tinker around the engine. Take some things apart.
Then you hold your hands in the air because you don’t actually know what you’re doing. You don’t even know how to put the engine back together.
Your (former) friend is now in a worse position.
Ok, this story is ridiculous. But it happens all the time in the real world. People make promises for things that they can’t actually do.
Manage expectations, foster trust, and only promise to do the work that you can actually do.
