Thank you for sharing this video, @gandhibaba! I liked all five lessons, but the most eye-opening for me was Simon Sinek's (his chair analogy in particular). The video invites us to suggest additional lessons, and one that I would add is: "Your destiny isn't ruled by what other people say about you." This doesn't mean it's okay to treat people badly. It means that when other people try to make you feel worthless, it's a reflection of some darkness going on inside them, not you. Trust that God or The Universe (depending on your cosmological framework) has put you in this world for a reason, no matter what anyone says (and even if you yourself haven't found that reason yet), and that the closer you are to living in alignment with that reason, the more happy and fulfilled you'll be.
