What things do you have on the back burner that you will get done someday? Are they important things like taking a trip to visit someone or is it time needed for a much needed downtime vacation?
Time flies by the older you get and saying you get these things done when this happens or when that finishes etc.
I can tell you from what I am going through with a few family members and friends, things can change very quickly. It's horrible how things have escalated with severe health issues.
Go take that trip you have been wanting to take!
