I think the first thing i need to do to start investing in myself is now to also work during school days. I worked for some months during the summer in 2019, but i only held myself back from spending money for only so long. It was a little difficult because of the clothes I wanted and things I wanted to do. (UPDATE) Now a little time later after spending all the money that was in my bank account, I think now is the time for me to not spend the money i have left but to look for a job and make some more money so I don't go back to when i had zero dollars. :(
