My mother loved fresh flowers in the house, but she rarely brought them home. She was never a gardener, I think it brought back to many painful memories of struggling on her family farm as a child. Her reasoning for not buying herself flowers was simple, flowers cost money and they didn't last long. She denied herself the enjoyment of fresh flowers to save a few dollars. In the end, the money outlasted her. A couple of days after I returned from her funeral I was in the market and saw fresh cut flowers. I bought a bunch - I have every weekend since then. You can't take money with you, you can't enjoy the flowers at your funeral. Buy them now, enjoy them while you can.
What do you deny yourself because it costs money, that you could enjoy if you wanted to?
