It would be cool if we had a self-improvement comm.
As leftists, we understand that a lot of individual problems are caused by systemic issues. However, I think that there is still a lot that can be done on the individual level to improve your life.
Most online self-improvement spaces have a reactionary slant and are dominated by the same type of guy, which is another great reason to have a self-improvement comm on this website.
EDIT: our awesome admins created the new comm and our awesome comrade @[email protected] stepped up to moderate it, please check it out and start posting: https://hexbear.net/c/self_improvement
Are there any improovers here? What would you like to improve in 2024? Would you like to have a comm where we can hang out? 
I'd say a lot of these are domino things. Exercising more makes sleep easier. Getting more nutrient dense food like veggies also makes sleep easier.
I completely agree. When I was in a depression, I kept falling into negative feedback loops - for example, you stay up late, then feel like shit the next day, eat unhealthy food and sit all day. That's why I'm trying to create positive feedback loops, which is what you described.
