There is criticism and there is critique. There is a difference. Assume positive intent. That makes life a lot less ugh.
Remember too -- Criticisim just tears you down for no constructive reason. Critique is constructive feedback on a situation.
If you say your goal is X, how do I think you are doing?
If your goal was making brownies? Well, I don't think pulling out ingredients for spaghetti was so hot and that shan't work well. Won't help you reach your goal effectively.
For your goals here -- you have it covered. You are doing fine. You are owning your own bag. WTG!
Hang in there!
