Draw a timeline of yourself, showing what you looked like at 12, 14, 16 and 18! :D If you're older or younger than 18, you can fit the ages accordingly of course.
If you cant draw and/or can't draw on the computer, no worries, it doesnt have to be a masterpiece. MS paint works too
Here's mine. I think I turned back into a 12 year old for the most part.
Feels good man
