My life purpose is to sacrifice oneself for the greater good of humanity. I feel like I will have more potential to do great things at a Tier 1 university. I imagine some professors exchanging insights at a lunch table, and I happen to be there. I might hear some insights that, unless I spend my whole life researching that topics, I wouldn’t know. Without a lot of insights like that, my growth will be limited. Then, I won’t be able to do something great that can help billions of people. My life purpose will be shattered.
