What year do you wish you could go back to?

I want to go back to 2012/2013 and live my life differently and make something of myself , j had a great time at school messing about and it was fun and it didn’t care that I failed every single class and was in trouble every week. But I also wished I had studied for tests and got good grades that could have helped me in the future. My science teacher said I was a capable student if I put in the effort I could succeed. But I didn’t around that time. 2014 I wished I lived a lot differently it was a shit time of my life and I wished I didn’t over study and make myself ill and I wished I didn’t let the bullies make me drop out of school. 2015 I honesty wished that I did stuff to make my life good instead of wasting the whole year finding ways to kill myself or harm myself. 2016 I wished I had put my money towards singing lessons and classes such as ice skating Instead of wasting my money on crap and things I didn’t need and spreading it all in one ago instead of saving it. 2017 I wished I had saved my money up for a good trip somewhere but I wasted it. And I wished I had a better time mentally at college. 2018 I just wished I had done more with my time and gone to more places. 2019 was I wished I didn’t trust so easily but 2019 was the best year of my life so very little regrets. So yeah I want to go back anytime Between 2012 to 2018.
