Sunflowers always make me happy. In fact I call them the "happy flowers." This year I grew my own. I've tried before but they would always get eaten. I thought it was the deer or rabbits but after researching, I discovered that it was actually the birds. The birds will eat the sunflower leaves when they are little/just sprouted. I put nets over them this year and they finally thrived.
Looking at my sunflowers makes me happy. Go see Leigh vs. Laundry to see more photos that will make you happy.
