Hi. Fmanie, never expect too much at the start, you can't run before you learn how to walk, it is normal when you miss things, that even happen in normal reading when you read ever single word. Remember this, We (human) never fail, we only have feedback so we can improve, we think we fail because we didn;t met the expectation of someone or something, the more we expect the more we (think) fail, hence, give up easily, so why expect anything, a baby wouldn't give up learn how to walk if he fall on the ground so many times. Why not feel confuse instead, confusion is good in NLP ways =)
