The current powerball lottery in the U.S. is now up to $1.4 billion. There's going to be a lucky winner tomorrow, and Mark Cuban has got some pretty sound advice you might want to take, and it applies to any kind of lottery you win.

The very first thing you should do is hire a tax attorney.

Don’t take the lump sum. That way you can’t blow it all in one spot.

If you are not a smart investor, put it in the bank and live comfortably for the rest of your life.

Say ‘no’ to friends and family who ask for money. It’s okay to help SOME of them but talk to your accountant first. Keep in mind: Nobody needs $1 million for anything. Nobody needs $100 thousand for anything. If they ask for it, they are not your friend.

If you were already an unhappy person, the money won’t make you suddenly happy.

If you were already a happy person, you will be even happier.
