Richelle E. Goodrich said this quote
“ Having this, we want that.Owning some, we want more.Standing here, we wish to be there.If it's impossible, we struggle to make it happen.Why are we like this? Why not be content with some, here, and now? Why is enough not enough? Because humans are ambitious creatures not meant to be idle or fruitless. We strive to learn, to grow, to achieve, to amass; therefore, we will never be content. ”
