There is a myth about the Bermuda Triangle. Rumors said that any air craft, airplane, object or human that got near the Bermuda Triangle might go back in time. Let's say today there is a choice to go back in time, will you?
If I am given the choice, I will decline the offer. If the 21 year old me were to go back in time, seriously what can I do? My family might not recognize me, nobody will to be exact. If a policeman were to come up to me to check my ID, things might go very wrong. Let's say I went 10 years back, the time when I was 11 years old. Then the policeman checks my ID, most likely he will be super horrified to find out that I am born in the year of 1991 and I should be a 11 years old kid instead of a 21 year old girl. I might be accused for having a fake ID.
Unless there is another scenario which I went back in time without knowing and there is only one me. For example like I knocked my head and I went back in time to the 11 years old little girl and is still that 11 year old me with no memory that I went back in time. Actually it really does not make a difference because the surrounding, family, peers influences and education that I went through will all be the same and I will definitely make the exact same decision for anything I do.
If I really do not have the choice and I went back in time as a 21 years old me, most likely I will go up to the 11 years old Abigail and teach that little girl how to have a better communication skills with other people, learn to open up to others more, learn what is self love and listen to my own opinions more. Maybe that little girl might not be a musician today...
That is a saying that the past cannot be changed, all we have to do is to live in the present and be prepared for the future.
