I wanted to share this article I found about 7 actionable changes you could make now to "turn your life around" https://zenhabits.net/7-little-habits-that-can-change-your-life-and-how-to-form-them/
Nothing happens "NOW" but we do start today which is about as "now" as you can get.
I agree with the article's top 2 habits.
1. Think Positive
I think by starting these two habits today, one can make a lot of positive changes in their lives. However, my #3 is NUTRITION because I don't think you're capable of exercising or thinking positively if your body and mind aren't fueled properly.
