An exercise in cringe

I got through the third exercise without a hitch. Then I read the dreaded chapter four entitled "Your Finger Painting Sucks" and that was when I was ready to quit. I have been writing every day for what seems like an eternity and this god forsaken book tells me to look back at my old writing. I read lots of very bad dramatic middle school love stories, which I wrote in the sixth grade. That made me cry I was so embarrassed. Other made me cry for different reasons ( I assume no one is reading this so I'll talk about it) because it was about me struggling to come out to people close to me.
 As I was looking through all of them I got to see my progress. The exercise asks me to imagine what my writing will be like in a year after I write everyday after thinking and writing about where I'm going to be in a year I see myself (hopefully) using a lot less commas (it's a real problem trust me) and using more sophisticated language more regularly.
The book asks me multiple questions like:
"What have you learned since then?" (as in the old piece you are reading)
"How has your writing improved?" (Fox Ch. 4)
Though both of those questions could have simple answer I took them to a much deeper level, as my life seemed to get more stressful and things begin to fall apart my writing seems to improve. So my writing has improved because my life has gotten worse (or more stressful I guess).
At this point I'm just rambling so I'm going to cut it off.
How have you improved in your life? What is something that really affected your growth?
 Stay tuned my dudes.

This is my reaction to sixth grade me.
