I've seen some posts here from some well-off members about investing and being worth high amounts. I know little about investing but will be earning alot more than I know what to do with soon.

I do pretty well for myself. Last year made just over $100k, this year about $110k with a change in employer. Next year will be about $90k, but after that it'll be $150k and climbing every year until retirement. I have about $35k in a standard savings account making laughably low interest.

This be company has a 401k with 16% compulsory company contribution and about $45k vested right now in my previous 401k.

My only debt is a mortgage on my house which is down to $80k owed and 3.5% interest. I'm making above required payments on it ($750 monthly payment, paying $1300/mo).

I've never invested outside the 401k accounts. What should I do next?

I'm 32 years old in US, by the way.
