If we all had a big eraser... would we use it?

there are times wen i was sure that i wanted to erase a certain thing or person... bt in the end, i wud leave it all as it happened. i may hav wished to have gotten out of a bad things happend earlier... or how i wish i pursue a different major, but in the end.... i am happy with my choices. ( execpt those sh!tty choices that i did, and i plan to never do it again. yup!)

i just generally look at the glass as half full now and i am happy to be where i am...
Did i do all that i could?
i guess that's the only question that i could ever have.
