Change one thing

if I could come back in time , I would change certain numbre of actes that I've done the last 15 years of my life. I would change my way of eating , my way of speaking , my way of traveling , .. I would change some friends by avoiding them at the first place , some others I would make relations with them ... lot of things to say .. I would stop some accidents that happened to some members of my familly , I would work harder in exams and get the hightest notes as much as I can .. I would show my parents some ways that they should do but they didn't , I would help some other guys to resolve some problems by the correct way.. and lots of other things ... to many to say at once .

being a nostalgic fellow, i will take a back turn to my childhood days (fantacy) I will change the way politicians work in my country (social) I will change my skills in interpersonal relationships (individual)

I would definitely take up the course that I like, and that's VetMed. I took up an Engineering course and I actually graduated already..but really, its not my first choice. So, if I could turn back time, I'll definitely take up the course that I like

I will change my age and get back into my teen age...as i love those moments
