Sometimes it just occurs to you, out of nowhere. There’s this moment of clarity that appears less as a thought and more as a state of mind. If the thing you think you’re done with has been a significant part of your life, you’ll want to take your time.
It’s possible that it’s a passing phase, but my experience says otherwise. Still, you want to tread gingerly. Keep it to yourself as long as needed to make a final decision.
Life’s too short to dilly dally.
You’re not getting any of this time back.
