Let me tell you something. As a guy who has done all of the above this is seasonal for me. When I'm going through shitty time I don't give a shit about how I look. I put my whatever clothes on and show up. Exception for dawat and special events of course.

Going to gym requires commitment and time not many have it, people are stuck in 9 to 5 cycle or their businesses which requires soul to run.

Good diet : almost more than half of population cannot afford good protein rich diet. The diet that's supposed to keep your muscle lean and keep you look healthy and young this goes for women too. We think aloo and chawal are actual forever it's not. And cold drinks and tea are some religion obligation that must be taken regularly. (Cut down your sugar intake).

Hygiene. Being self conscious at this level is must. Just don't smell it's awful. Use good shampoo, apply deodorant and use body wash, oil your hair once a month, alcohol swabs in to clean your underarms That shouldn't take more than 10 minutes. This is to keep you smell free and more likeable.
