Ohhh yes, I think many of us are familiar with this mindset! I have been escorting for nearly 7 months now and have very little savings to show for it. I went a bit mental at first because I have NEVER had resources like I have now. All my bills are paid on time (again, a first for me) and then i would just spend everything else: holidays; clothes; shoes; jewellery; beauty treatments; expensive beauty products.
Last month I just sat staring at it all and yes I felt happy to have them but I would rather have savings for the future. So now I pay X amount into one bank account to cover all bills, Y amount into another bank account for personal spending and then the rest goes into a savings account. So I set myself a weekly target. I know I have to make Z amount each week to cover bills and personal spending, then I know whatever I make above that goes to my savings. It works well for me because I have allowed a little for those indulgence items, if I want to buy them, which means I am less likely to tap into my savings when I see that gorgeous bag that I really must have or else my life will never be the same :-P
Ps, prepaid credit cards are great for savings.
