The other day I painted my nails. It was something I had been meaning to do for quite a while but something always stopped me - I would be having a shower later or washing up and it would ruin painted nails so there was no point. After a few weeks of this I realised that if I continued to worry about ruining the nails I would never actually get around to painting them. I took the plunge and spent a little 'me time' to indulge in beautiful nails. They haven't lasted but they made me feel so much better for a few days, and I can always paint them again.
I find the same is true of scented candles or expensive soaps that we are given for birthdays and Christmas. We don't use them, we save them for a special occasion. But more often than not they will have lost their scent by that time and the gift has been wasted. The thing is, we could always get some more soap if we enjoy it, so why shouldn't we use it. As far as I'm concerned we only get one life and it's the little things that count. We should treat ourselves as that special occasion and enjoy the small pleasures we can get out of using luxuries. Treat yourself instead of wasting the chance, and I promise that you'll feel much better and happier for it.
