If you could go back in time and tell yourself something what would it be?

Let's say there was a way that you could go back to a version of yourself in the past for just 5 minutes and whatever you do would affect the future of your reality, But there are rules like :

1. You would have to pick a time and place you know he/she will be alone.

2. You can't bring any materials with you like journals, pictures, electronics etc.

3. You can't reveal any major global future events.

4. Obviously can't kill yourself or anyone else.

Would your risk changing your future for better or worse?

What advice would you give yourself?
