I’ve never been much interested in the past (which I think is different than “history”).
Regardless of whether your past was good or bad, if you live in it, you’ll most certainly become unhappy. Either unhappy because it was terrible, or unhappy because it was so great, and presumably, your life now doesn’t live up to that.
If your past was terrible, you should look ahead to the future.
If your past was great, you should look ahead to the future.
But I do think you can learn valuable lessons from your past which enables you to look ahead more effectively.
Just don’t live there.
