I get what you mean, but there is hiking, surfing, video games if you pirate, tons of hobbies cost very little long-term or reduce already existing expenses, like cooking or riding a bicycle/motorcycle instead of driving (assuming you go all in and don't also buy a car, relegating the 2 wheeler to "toy I use when the weather is nice".

Jesus Christ, go play some soccer or cricket. You people make the shittiest excuses and stories.
