This is an eternal question with no specific answer,Just individual entries.We will be all in that box at the end and then nothing matters more than how one lived his life.Live it fully,with awareness, so you don’t hurt yourself or others.One does not need big ideologies or fancy philosophical headings to live it.Awareness,creativity,consciousness,they may help,but enjoy the journey without wasting too much time on knowing things just for the sake of knowing them.
