All you need to spend $$$ on is:
rent (share bigger bedroom homes to save)
food (never go out.. cook simple healthy stuff)
internet (cheaper options: big downloads at night while sleeping)
Entertainment should be 100% free:
chess, classical literature, memes, text books, walks while listening to music, beach etc
Fitness: AVOID the gym! ($$$ + cramped, sweaty, etc)... go out, fresh air, sun, body weight exercises in the park.
