Just think for a while, what we will get after pretending to people that we are happy, satisfied and living a fulfilled life, if we are really not. Instead, we must search for the causes and make the things work out, as we want. If all of us are Happy, then why we need to pose ourselves. We must look natural as we are. So, in short, be yourself, you are the unique piece on which god had given time while manufacturing. So, he must not feel regretted after looking at your deeds.
