If you had 400k, what would you do?

I am a 25 year old guy living in the USA. My parents just became multimillionaires (10 million) and will be retiring very soon. My parents decided to give my two older brothers and myself 400k each. I currently have the 400k in two High Yield Saving accounts. As I don’t want to rush with it.

I don’t have any kids nor am I married. I didn’t go to college nor do I plan to. I’m currently working in sales and I’ve been in sales for about 3 1/2 years. I make 100k a year and since my first year in sales I managed to crack 100k every year. I do want to pay off my debt which I currently have about 65k in debt in credit cards and my car loan that I had bought brand new last year. (23’ Lexus IS 350 F Sport). I do want to use 20k max to travel to multiple countries all around the world. I live in one of the most expensive states in the country. So I currently am renting and I do plan to rent here for a few more years. However, I don’t plan to live here in this city for long so I don’t want to buy a house here.

What would you do in my situation or any advice? Thank you.
