Make your yes mean something. A yes that flakes half the time is just a maybe with better manners.

Agreeing is easy in the moment and expensive later, which is why so many people say yes to dodge the small discomfort of declining. The cost lands on whoever planned around you, and then on your own word, which gets a little lighter each time. A dependable no is worth more to people than an enthusiastic maybe, because they can build on it.

Before agreeing to anything this week, picture the actual evening it will cost. If you can already see yourself cancelling, say no at the start. One honest decline is easier on everyone than a polite disappearance.
