Start now instead of five years from now.
I wanted to learn to quilt as a teenager, but put it off as school, work and family took up so much time and energy--I could have been doing this for an extra 47 years! Now I'll have to live another 40 healthy years to use up all my fabric, which will be great if it happens, but also a miracle with headlines such as "Congratulations, suzanprincess, on celebrating your 109th birthday and still happily making quilts!"
