I get excited sometimes when I’m feeling happy but then I think about the costs of the course I can afford it

It’s $25 a week $515 for 5 months I get paid $30 a day and $40 on Monday but then I have a gym membership that finishes in 17 more payments I’m paying $32.22 a fortnight, and then I have iPad and a iPhone to pay for every month, which is $50 each a month, how am I supposed to to pay $25 a week, do you think I can do it, or should I save up till February
