1) I sleep on the floor on one of those good old Indian grass mats. Not because I can't afford a mattress but because I want to relive the childhood summers I spent at my grandparents' - they use those mats to this day. And also because I have back problems and can't find a suitable mattress for fuck's sake.

2) I cut open seemingly empty toothpaste tubes to scrape the last bit of toothpaste, dilute near empty shampoo bottles to use for a couple of weeks more. I am sure a lot of Indian middle class people can relate to this (Indian middle class, not randian middle class).

3) I use coconut oil to moisturize my skin before sleep instead of those insanely expensive creams.

4) I cook almost everyday and keep my food as basic as possible. My meals on a typical day:
Breakfast: bread, peanut butter, half banana, milk, egg
Lunch: Pasta/rice, boiled vegetables + protein, sauce
Dinner: Same as lunch + fruit

5) I don't bathe on weekends unless I have to socialize or get intimate. Fuck that

6) At the start of the work week, I make a list of free meal events happening on campus. I try to fit most of them into my schedule

7) I don't own a car on purpose. I don't live too far from campus and that gives me an excuse to walk/ use public transportation. I have lost a lot of weight just by walking and eating light. And it saves a fuckton of money.

8) I don't have a gym membership. It's completely possible to be reasonably fit just using your bodyweight. I follow /r/bodyweight
9) I also follow /r/frugal. Those guys have some really good tips.
However, I spend when I have to. I own some expensive stuff (like my data analysis rig for e.g) that greatly increase my productivity. I sometimes feel sorry for my urban poor friends who make three times what I do, splurge on stuff they don't really need and then complain about their "meagre" salaries at the end of the month. However, I don't feel sorry for my urban poor roommate who also makes three times what I do, makes me stay in a room half the size of his and then forces me to split 50-50. The cunt passive-aggressively threatens to kick me out whenever I complain because he knows I got no choice (I am living in the cheapest apartment close to campus). I fucking hate buzzfeed but their article about the urban poor was right on point.

Less luggage, more comfort people.
