First of all, just saying, a $60 guitar is probably really bad no offense. my first guitar was 60, and it was absolutely horribleeeee. That's just my opinion.
But for your money situation, what I do, when I save up for something, ( I make $24 a week) and I put $20 away each week, and it adds up very quickly. And then I hide it in this deep dark secret place in my closet, with a note on top of it reminding me not to spend it!
It works perfectly for me.
So in your case, I would put a big percentage of money that you get each week away, and hide it some deep dark secret place, with a note on top reminding you to not spend it!
I hope that helps buddy(: good luck!
When I got a job they put the money right in the bank instead of a pay check, and ask if I wanted it in savings or checking account...you could see if that is possible...and a $60 guitar is probably not very good, just saying (but it could work as a beginning guitar)
