I first had to Google the word “constraints”.
Basically, Constraints = Limitations, so what would I do if I had no limitations? Having no limitations means being able to do everything.
Having no limitations means not being limited to the laws of physics.
What would I do with this “superpower”? I will take the task of pushing the human race forward, I can venture everywhere, know everything, so also knowing the future. I will make this beautiful piece of Globe an even more beautiful piece of Globe.
Not only that. Just like Tan Lyn said:
I will enjoy life. I want to live. Go everywhere in the Universe.
