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 @SeventyTwoTrillion@hexbear.net 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? 
That's a good list, I have some of these things on my list too.
My pro tip is to try making a bit of progress almost every day, no matter how tiny. Nothing is too small. Just having that feeling of "I am making progress" is really motivating to me.
My other pro tip is to track your progress.
I do it by journaling. It can often feel (especially on bad days) that you're stuck and not making any progress at all. I have made some really good progress in the past few years and the only way I'm aware of that is because I've been writing stuff down and journaling. If I didn't do that, I would feel like I haven't made any progress.
