A quote from Gay Hendricks (from his book, The Big Leap): You'll never have enough money to buy all the stuff you don't really need, and you'll never have enough time to do all the things you really don't want to do.
I want to focus on the second half of this quote. Time is something we create--it is not outside of us and we are not victims of time. Think a while on that statement by Hendricks about time. It causes us to truly evaluate what we want to do with the time we create, and to take responsibility for saying "no" to those things that we really don't care to do. Just like anything we create, time is valuable, and it supports our happiness (and the well-being of the world) when we are doing those things we truly want to be doing.
Here's a different option relative to time: Instead of saying, "I don't have time for that" (whatever "that" is), say "That's not how I care to spend my time right now" or "I prefer to complete this task before I do that." This makes your use of time come from a personal choice standpoint rather than from a victim standpoint. This is much more empowering behavior.
I feel passionate about sharing these ideas, so this took almost no time to write!
