What are some healthy habits?

Hi everyone, I have been trying to build some better habits lately like exercising regularly, reading more and reducing screen time but I always seem to lose motivation after the first week or two. I will start strong then slowly slip back into old routines. I have read a few wikiHow articles on habit building but I am still struggling to stay consistent once the initial excitement wears off. Does anyone have tips or strategies that actually work when motivation dips? How do you push through those off days when you just do not feel like sticking to the habit? Would love to hear what is worked for others—whether it is routines, tracking methods, accountability or anything else. Thanks in advance.

I´ve taken a lot of quizes and they all say i have some brainrot, but im barely online and other kids at school are infecting me! Help!

Now that i'm not in school I feel like I'm not learning many new things anymore? Idk, I feel like I want to be a "lifelong learner" type and want to be more in touch with that side of myself but life always gets in the way. Would love tips for feeling like I'm using my brain more and learning new things!
