In Gretchen Rubin’s The Happiness Project, she talks about ‘spending out’ as an element of happiness: expending and using up the things you love and not hoarding them. This can also be true of ideas, keeping new toys in their boxes until you're ready to play with them, and saving new drawing pencils until you feel you are good enough to use them. The example Rubin uses to illustrate this sentiment is her Grandmother’s perfume. Her Grandma kept an unopened bottle of her favorite perfume on her dresser, explaining to Rubin that she was saving it. The day after her Grandmother passed away, Gretchen collected the beautiful perfume bottle and now keeps it on her desk as a reminder that, no matter how beautiful the bottle, the day you are saving to use it up might never come.
