Hello everyone! I am planning on moving out of my family's house soon enough. I will be making about 2400 dollars after taxes. I work extra full time (60 hours a week) plus pharmacy school. I don't feel like that's enough. I do have a budget set up and I am estimating that I will have 500-700 extra a month.

Here is what I feel like I should do if I have 600 dollars extra a month.
add an extra 100 dollars to my saving account.
use acorn(investing app) and invest 100 dollars in there.
Maybe start putting some money in my 401?
What else should I do?

What other forms of investment are there?

I was thinking of opening an ebay store but with my current schedule I wouldn't have that much time to run it. Any ideas?? THANKS!!
