Just because you have or think you have a long way to go doesnt negate how far you've come.

I dont know if what I am going to say will help but because I dont know you very well I will share my experience. I get that alot myself. My default setting seems to be that I focus so much on how far I have to go and all the things I messed up and need to do better that I forget that if I could do this all already I wouldnt need T. Therefore, yes I need to learn from my mistakes but that doesnt mean I need to kick myself everytime I dont do something "perfectly". Its not wrong to admit when you do something wrong. Is it really that its wrong or just that it doesnt meet your standard for where you should be? I know that for me it not normally wrong but more that I dont feel it is "perfected" enough. If this makes no sense just ignore it...hope this helps.
