Thinking about moving to Dallas, what should I know first?

I’m considering moving to Dallas in the near future and wanted to get some perspective from people who actually live there.

A few things I’m curious about:

What neighborhoods are good for someone new to the city?

How bad is the traffic really?

What’s the general cost of living like right now?

Any areas I should avoid when looking for an apartment?

Also just generally wondering what people like (or don’t like) about living in Dallas.

Would appreciate any advice or things you wish you knew before moving there.
