writter or just plain dreamer?

list of my problems at writing something:

1. Putting all my thoughts into writing.

2. My basic subject verb agreement.

3. usage of their/there, to/too, and some of their kinds, well all I know is those are homonyms.

4. I don't review what I type.

5. i think i have ADHD, so every time am writing something after a few sentences i forget the next lines.

6. i don't know how to focus on one reader that's why all that I right are like chopsuey(mixed vegs)

7. what i think is interesting would turn out boring after i put them into writing.

8. lastly, i don't want others to read my writing in front of me, because I don't really know how to accept criticism.

So now am trying to right every time i can, just to fulfill one of things that I failed to be good or even just be decent at..
