My why
In my life, there are things I want to explore to its frontier.
Sure, there is the altruistic or noble reason of wanting to elevate and impact people but also because chasing that frontier is when I live life most vividly (aka most interestingly).
If I didn't live life in a colorful way, guilt and shame would live permanently in the back of my mind. Constant thoughts of "what if" or "just start" would consume my mind like a parasite, so I might as well tend those seeds of curiosity while I still have the chance.
