save my money

I need to save my moolah so I can get an apartment withtin the next month 1/2

Oh my gosh! I don’t know why this is so hard for me to do. I’ll be doing good for a little while and then I’ll get this itch to just spend spend spend. I was thinking I should keep a journal of all that I spend my money on and that way I will be able to see at the end of the week or month what I waste ny cash on the most.
