I'm going to keep twenty dollars for myself
What is your plan for that money?
Alcohol, food, meat, cigarettes, sleeping pills, weed
While it is okay if you want to keep money for yourself, it isn't okay to use that money to buy drugs such as cannabis and sleeping pills without a prescription. Not only is doing so illegal and can get you into trouble but it will negatively affect your health. Instead of using the money to purchase vices, use the money on healthier pursuits and hobbies.
That's expensive.
I think that you should try to find a better way to spend your money. I think that it is wrong to spend money on illegal drugs.
