I have not developed it completely yet but am able to do it most of the times

It is less about the ostrich algorithm and more about not getting affected by smaller things.

Our generation is mostly on the extreme ends of getting affected by things, either they don't give a F or they get affected by each and every small thing; there is hardly anyone with a balanced perspective.

If you are having bad moments instead of the days then you aren't nonchalant.

If you don't give a F about anything then you are nonchalant.

And anyone can gaslight you for that.

1. Limited Screen Time
2. Minimum 6 hours of sleep
3. Move your Body daily
4. Talking/spending time with loved ones (Family/Bae/Friends/Similar)
5. Do something you like daily (even if it's just for 5 minutes e.g. listening to music)
6. Eat as much healthy as possible for you
7. Keep yourself hydrated
8. Connect with nature as and when possible (The new word for it is touch the grass if I am correct)
9. Don't stress about not being able to do any of the above things, do as much as possible and as & when possible.
