One of my teachers gave me a great tip:
Make yourself do the dreaded chore for 15 Minutes. Set an egg timer and work on the "whatever" project until the timer goes off. Then you MUST quit. Do that for a few days and you'll be back on track.
Another option: Do you have a UFO that could benefit from a helping hand and an hour or two?
OR: if all your projects are large, make something you can FINISH and feel good about yourself and your work.
Or give yourself permission to take a little break but keep checking this forum. You'll soon be so jazzed by everyone else's success, you'll be running to your sewing space.
