While I was giving a time to my studies of Qt, I found this text in a tumblr:
"Just when I think I have learned the way to live, life changes and I am left the same as I began. The more things change the more I am the same. It appears that my life is a constant irony of maturity and regression, but my sense of progress is based on the illusion that things out there are going to remain the same and that, at last, I have gained a little control. But there will never be means to ends, only means. And I am means. I am what I started with, and when it is all over I will be all that is left of me."
