Overcoming the Haircutting Learning Curve: How Long Does It Take to Become Proficient?

Question
I have been cutting for about 3 months now and I am still struggling with some cuts.  I have been frustrated for about six weeks now that I am not getting any better and really don't know how to correct the problem.  I have zero confidence and at times I am afraid for anyone to get in my chair, for fear that the cut will not be good.  I am considering give up.  My question to you is how long (on average) should it take to reach a level of proficency?

Answer
Hello Jerry well let me first say DO NOT give up the more you cut the better you will become also put faith in your self if you feel you can't do it, then you can't, But like I said the more heads you cut the better you will get you have to develop your own style of cutting which can take a while but like I said the more heads you cut the better
