Pick a time when you wanted a sewing machine and learned all about them in sewing machine reviews and how to get the best model for the best price. You can still do that and you can even use those same machines that you started out on to help others. You can donate them to charity or you can give them to someone you know would otherwise be unable to have one so that they can learn the gift of sewing as well.
Sewing is a talent that you can develop if you practice. It is just like any other skill or talent if you practice often you can and will get better. If you leave it up in the attic to collect dust you will not learn anything and you will not be able to help others in their quest. Keep your goals in front of you and get the things you need to make them happen and before you know it you will be a pro.
