My little nephew and I planted flowers in a window box together last spring. Week by week he would come and visit and check on it or call asking me to send photos of the little sproutling and how much it had grown to his mom's phone. The progress was exciting. Watching it go from little seed to full-grown plant was amazing to him. The excitement he felt for growth is probably similar to the feeling you feel when you track your customer growth with your company. There's a pride in seeing the numbers rise and letting it resonate that "hey, I did that".
