It is easy to let your thinking run in that vein.....I'm 75 and aware of it !!!! but....I try to set aside the "down" side and realize that a month, a week, a day is still time to get things done....I see people much older than I am and they are going strong, so I take heart, and get to my quilting knowing someone is going to be so grateful that I did!!!!wishing you joy in your todays and tomorrows!!!
