Bret Michaels says: “You don’t know what you’ve got ‘til it’s gone”, and this is true. After living in a large house for a few years, economic problems forced us to leave it for my grandmother’s house, where I had to share a very small room in a small house with my sister and the rest of the house with 6 other family members. This was hard at first, because I missed my old, spacious house, but I got used to it even though studying was still hard.
We stayed there for over a year and then moved to an apartment in the city, where we live now. I don’t have a room there and sleep in a bed in a nook of the hallway. Such close quarters make studying there challenging.
My junior year began with my grades suffering, as a result of working 6 hours after school more than 1/3 of the school days, getting home at 10, and hectic conditions at my house. At the end of the winter term, I realized that I wanted so much more than what I was doing, and I suddenly had the drive to really turn things around.
I began going to the library to study, away from the apartment and its distractions. I was also diagnosed with A.D.D. and prescribed medicine to deal with it. Immediately, my grades and attitude began accelerating in the right direction.
Words cannot begin to describe how pleasing it was to start tackling each assignment one by one, and to be on top of everything. It felt like I was reborn in the New Year. Instead of spending a half-hour to an hour maximum studying, I spent hours each night, often from when I got home at 4 o’clock until everyone else was in bed. I actually wanted to do all of my work. I was just enthralled at how well I was doing, and had a new outlook on life altogether, and felt like I could do anything.
I had a new-found love for Geometry, and its step-by-step logical solutions for everything. It all seemed tangible and applicable to real life. I spent the most time on this subject, and it quickly became the highlight of my year. I went from having a C/C- grade in it in the first two terms, to having a flat A in the third term, during which we learned the most complicated concepts of the year. After the first week or so of my transformation, my teacher asked to talk to me after class, rarely a good omen. She asked me “What are you doing different?” in a confused voice, “because this is fantastic,” holding a piece of my homework extra-credit with a complicated problem that took about an hour to crack. I could not contain my smile. That was the point of no return; never would I go back to just sliding by.
While not every class that term flipped to an A, most improved a notable amount. Now, in my first term of senior year, I currently have an A/A- in all of my classes, as of December. I am positive that I can keep this up the whole year. I achieved something I had never done before in high school, and will do anything to keep this. After experiencing the joy of such a turnaround, and after receiving praise for my work instead of criticism, I can never go back to my former habits; it took too much to get here.

It sounds more like a speech class presentation than an essay. What's the class?

And it's really cool that you've overcome your problems with ADD. I'm currently not medicated for my ADD. I guess I have a phobia of meds tampering with my creativity.

It's the essay that I will be sending to the colleges that I am applying to.

Ask your doctor if you could start at a low dose, and see if you like it or not. It (adderal) really doesn't feel to alter my creativity. If anything it works for the better for me. But hey it's your choice haha.
Thanks
