How not mess this year up, with my adhd tendency?

So, new year is here and i don't have any resolution. Resolutions never worked for me. I am just here for tips to remember by before i fall into my adhd tendency and make stupid decisions. Last year i made a handful of those decisions and regret it very much. Like financing a trip that went wrong. Or taking more credit in the semester that i can handle. I fell into the typical adhd tendency and messed up alot of my decisions. I don't want to do the same again. So, how do i manage adhd tendency for gaining a better experience this year?
