"If some one loves a flower, of which just one single blossom grows in all the millions and millions of stars, it is enough to make him happy just to look at the stars. He can say to himself, 'Somewhere, my flower is there...' But if the sheep eats the flower, in one moment all his stars will be darkened... And you think that is not important!"
(Antoine de Saint-Exupéry's Le Petit Prince)
Have you ever killed a house plant because you forgot to water it? If you have a plant in your office or in a bonus room it is all too easy to forget. Take a photo of you house plants, set how often you want to water each and get an unobtrusive reminder. You can set the time of day when you want the reminder to appear. That's it!
