Life as we call it is an entity. It is so vast that we are a mere speck of dust on the dust. You need to think carefully about everything you do/have done in this life. Was it worth it? Did you achieve something so grand that you excreted serotonin out of your brain? Did you help everyone your eyes laid upon that needed help? Do you work on yourself to become a higher state of being? Are your parents proud of you? Do you have everything planned out? Did you respect yourself and all the decisions you made?
Do you regret anything? Are you trying to become more wealthy with knowledge? Did you use all your cards? Be humble fetus.
