signing skills

When i see how i am signing, i feell like i am being clear but i still am usure of my signs. I am still not comfortable about signing what i think i am supposed to sign. I nedd to stop second guessing myself and make the mistakes so i learn. I think i need to get a tutor, but i have seen a big change in my signs since i have been here. Signing on the webcam for thirty minutes was hard for me to do. I know i didn't have thirty minutes, but even seing me sign for ten minutes is exciting to me. I am starting to catch on to signs, though i have noticed i need to stop starting my questions with "i have."
