I too, struggle with this almost daily! It's funny to me, that when it comes to some things, I'll spend money like it grows on trees, but with other things, if I can't get it on clearance, or with a coupon, then I won't buy it. For me, all I have to do is remind myself that the majority of wealthy people didn't become wealthy over night, that had to work hard, scrimp and save, and then when they became wealthy, the didn't change their spending habits. I want to be more like that, and only splurge every now and then. However, right now, I'm more into the splurging, and only saving every now and then.
Also, for me right now, I think it's going to get a little easier, even with Christmas coming, because, my father in law, and my brother in law (Brian's brother), both have cancer, and Brian will be getting checked for colon cancer sometime in the near future...how's that for motivation?!
Just keep telling yourself it will be worth it in the end, or perhaps, play a little game with yourself. Test yourself to see how much money you can save between now and a certain date you come up with. Make it a game...make it fun....look for ways to make cuts here and there, that you maybe had never considered before. Good luck!!
