There will be a cost to everything additional you say "yes" to. It might be inconsequential, or not. Just be informed.

What has to give to say "yes" to the new thing? What new skills, resources, or assistance will you have to acquire? How much attention and energy gets diverted from something else, and is that something else more important?

What's your purpose and mission? While not every single thing you take on must flow into your mission, the vast majority of your work portfolio should all complement or support that cause.

Asking "What's the point?" brings you back to what the completion of that work serves. If it doesn't matter enough, or at all, you know what to do.

Be cognizant of what work simply must not end up on your plate and why. Remembering the why is the key here --recall the emotions, pain, and price associated with taking on the kind of thing you said you wouldn't.

Even worse than taking on work that might not fit with your overall mission is work that you pointedly told yourself you wouldn't get sucked into, but find yourself getting sucked into.

We often say "yes" just because it's so much easier than saying "no." It's human nature.

So capitalize on that tendency by asking yourself if there's a different "yes" you can give so you can maintain the spirit of the affirmative.
