HOW I BUDGET MY PAYCHECK AS A 20 YR OLD SERVER LIVING AT HOME

I'm currently in Paris, so my paycheck is a little bit smaller than it usually is. I got paid $1,678.87. 750=ROTH IRA, 750=BROKERAGE ETFs/STOCKS QQQ VOO SMH META LULU APPLE. I don't even get back for my trip for another three days. I'm setting $100 aside for gas. 78=STAYS IN MY CHECKING ACCOUNT. I'll have $78 left sitting in my checking account. Fun money, emergency money, whatever I need. But I do have a little bit of cash, not anything near as much as it gets tipped on the toast. But I have $500 cash deposited when I come home. Stays in checking account/invested sometimes. I'm going to deposit that. I'm gonna have that money sitting in my checking account, depending on how much money I spend when I get home, but it's not that much money. I'm putting $100 on gas. So that's how I am budgeting my paycheck for the next two weeks.
