Firstly, well done on your post Evie.... I like your thought improvements for thinking style.

No Evie, you don't need to do a lot more work, you just need to constantly continue forward and learn as you go. There is no real quantity as such, more just time and the condition you must continually work upon yourself to improve. You found a negative, learn and then next time you may / may not make the same mistake; though its only a mistake if you decide it is one for you. If its not a mistake in your mind, then it is correct.

Your choice... a wonderful thing that. IMHO, I agree with bec though... it is a negative you ended with... but that is my opinion only. I also agree with Bec in that you do deserve the support, just as every other person here deserves.
