I feel this way a lot. I am a fairly frugal person and have always been a saver. I assumed being a single mom all these years contributed to that but years later I still suffer from buyers remorse. I still drive my 2006 Camry and haven't had a car payment since 2009. This struggle is worse with large purchases of course but to a smaller degree with little purchases. I have talked here about my knitting obsession but I have a decent size stash of yarn and when I buy more of the beautiful soft squishy stuff I get home and have a little guilt.
To try and maintain balance I work with a budget similar to Dave Ramsey and have my own entertainment budget line item that I try to stay within. If the money is allowed for entertainment well then yarn /knitting paraphernalia fits that category. Do you have a budgeted amount to spend on yourself? If so, enjoy those little splurges and have someone over to dinner to enjoy those new dishes!!
I will happily come over for dinner and ooh and ahh about your dishes and you can come over and oggle over my yarn! Deal? Lol
Well I don't ooh and ahh or oggle very well, but deal. And yes I actually did go through and divy up my savings in a budget, it's still not as detailed as I'd like but helps me have permission to spend on medium value things ( dishes, furniture, new clothes, etc.) rather than stressing that every cent saved should go towards the really big ticket things (hoping to replace my 2006 car sometime in 2018, we'll see how long it takes me to spend that much money at once since it's going to be quite a bit more than dishes).
Yeah I'm a chronic saver too and years of mom's "we don't need it" and then years of being an aspiring missionary with never enough support have probably only reinforced the whole save up until the money stops coming in and you have to spend your savings mindset. Fortunately I'm a pre-feeler so once the decision is made I don't waste time feeling guilty over it. Truthfully I probably won't even miss the money and will enjoy the dishes.
And yes everyone is welcome over to the cinder cave (men get man caves, I get to nickname my 500 sf apartment the cinder cave) for dinner and to admire the new dishes when they arrive (the fact that it's on the small side and will probably feel crowded with 3 people inside is no reason not to pack us all in like sardines so we keep bumping into each other while trying to eat or move).
