D.,
Our number one factor on whether or not to buy something is "Do we have the cash for it without affecting our savings?" That includes cars - but we do pull from a special fund for cars.
Yeah, we don't have nearly as much junk laying around as most people, but less to clean - right? We don't eat out much and swap babysitting when we can. I keep my eye out for free coupons - free dinners, free massages, free oil changes. It all adds up.
When I really want something for myself, I find a way to get it. Find some things you have but don't want and sell it on eBay or at a garage sale or used kids items store. I needed new pants for my kids but didn't want to spend a lot of cash. So I rounded up a bunch of old baby clothes and toys no one needed any more, took them to Once Upon a Child. When all was said and done, I owed $4.00 cash and got about 10 pairs of pants.
I also decided I wanted a front load high capacity washer and dryer for Christmas. I did my homework - a lot of it - and found rebates from the store, from the manufacturer, the electric company. I found coupons and sales and discounts. In the end, I picked up a brand new set for under $1500 - almost as low as a regular set.
I hope your cosmetic business is very sucessful. Make sure to set aside some of the profits to splurge on yourself. And yes, I think we are all dying for a little spring here! I just moved to MN in December from the south where 45 degrees above zero was "an unusually cold winter day." I am learning that "cold" is a very relative term. :)
Good luck,
S.
