Does this thesis sentence sound right?

For my homework I have to revise/edit a rough draft from my textbook. is the following thesis statement ok the way it appears or should i change it? it sounds kind of off to me but not sure how to fix it :

“Quitting school was not a bid deal for me until I realize all the effects of quitting would bring to my life. ”

the essay then goes on to list personal examples/experience that the person went through which prove that quitting school was a horrible mistake.
