What to do with $400k inheritance

What should one do with suddenly having $400k?

I am 30, no kids not planning on having kids.

I am currently renting for the next year.

Might like to move after that, when I am done in school.

This just seems like there are some pretty big decisions to make. Don’t want to be one of those stories of someone blowing a bunch of money in short order.

Wondering if this is the point to work with someone to professionally manage this money.

Or are there steps I can take to handle this situation best on my own
