We have a tendency to complicate things. We get caught up in stuff that doesn’t matter. The time we have is short (even though it doesn’t feel like that) and uncertain. Guarding it means being able choose wisely.
We don’t say no because we are unable to see what we are losing. That which we cannot see, we find hard to acknowledge. Things that come for free (e.g. endless social media feeds) have a huge invisible cost.
No is not just about “saying” it to others. It is about the “choices” we make to improve the quality of our lives.
