there are several.

I remember this one lady saying that if she had it to do over she would do most things differently.

I asked her why and she said - "because I know how this life turned out".

I asked her if it had been bad and she said no. But if she were going to do things differently she would lead a whole different life to see how it turned out.

I’d have had my name changed to Fabio so I was famous before he was.

I would apply for a patent on the time machine.

I would definitely tell myself to avoid every single one of the boys and men I was so obsessed with.

I would find 8 year old me and introduce him to Rudyard Kipling's Poem "If". I discovered it too late in life. It really would have helped through those school years.

I never took that first drink.

Would have never met the guy that wrecked my life.

I wouldn’t make the same mistakes that I did with my first proper girlfriend. I was so in love with her and too immature to behave sensibly. I’ve made loads of mistakes, but that’s one that really stands out.

Absolutely nothing, even the bad stuff ended up being good in the end. 😌

The need for people to keep asking this question

Baby Trump

I probably prevent myself from meeting very mentally draining people.

I probably tell my very young self to listen to your dad and lift those damn weights, for the love of god.

There are so many things I would love to change if I were able to go back in time.

Religion.

Specifically the Christian version of religion.

Ignorance is not good!

i'd want to change so many things but you cant go back, you can only attempt to alter the future instead after learning from one's past mistakes

Nothing

No
