First of all evict all of those negative messages running in your head from your mother, sister, aunt, friend, lady in the market or anywhere else you (and I and most people) have collected them from. What you do and when you do it and how you do it is right for you and don't let anyone tell you diffrently. If you only have energy to sew 10 mins a day then that is what you should do. There is no right way and wrong way to sew. Sewing is something (I have found for me) that you need to be in the mood to do. If I force sewing I will screw it up every time. Relax, this is supposed to be fun. Maybe a glass of wine first.
