I like the question, If not now, when? It fits for so many situations. When clients face turmoil over career changes and talk about their yearnings and the desire to follow their dreams and their passions, I often ask that. When women talk about longing for some "me-time" and some self-care time and in the same breath, cite their long to-do lists, I often ask it.
When I come up with excuses to not do something I really need or want to do, I ask myself that question.
We don't know whether we'll even have a tomorrow. All we really know for sure is that we have this very moment. Because of that, it just makes sense to make the very best use of this present moment that we can. Insofar as it's possible for you, allow yourself to listen to and follow your dreams, longings, desires, yearnings.
What's missing from your life? What is on your bucket list or thimble list that you really, really want to do? What's preventing you?
Think about what it might mean to you if you had that thing on your list. Think about what it would mean if you never got the chance. Now how much do you want it? Go ahead. If not now, when?
