[Question] Gifted $1 million. What to do? (Not hypothetical)

I recently was unexpectedly gifted a little less than $1 million in stock. I am speaking with a financial advisor, but I want EA advice.

What are my most important next steps? I want to be part of doing the most good possible for living, feeling beings before I die.

I know this is very personal. It is different for each situation. What are the most important factors to keep in mind? I am open to radical thinking, but only if it can be practically implemented by an ordinary imperfect person.

Thank you for your time—I am serious about this.
