which one do you like better?

Question

I need to write someting that would be quoted in my school's yearbook and this is what i have so far, tell me which one you like better and what would you change (if anything) about all of them.
I asked this same question in Polls and Surveys but i need your opinion as well.
Thank you so much!
This is really important to me!

Quote 1: When someone tells you that you cannot make your dreams come true, prove them wrong.

Quote 2: When someone tells you that you cannot achieve your goals, prove them wrong. (the only thing that changes is goals)

Quote 3: When someone tells you that you cannot achieve your goals, prove them wrong.

I know they are repetitive but they'll use just one and i want to give them the best one out of these.
Thank you again! =D

PS: should i change "someone" by "somebody" ?

Please keep in mind that teens ages 14-18 will read this so I thought it should be a little bit informal.

Answer 1

I like the first one cause It's nice and inspirational.
But it's a bit corny, I would put it as:

"People always put you down, show them what you can do!

But you don't have to choose mine, I still like the 1st one.

Answer 2

Quote 2: When someone tells you that you cannot achieve your goals, prove them wrong. (the only thing that changes is goals)

Quote 3: When someone tells you that you cannot achieve your goals, prove them wrong.

2 & 3 are the same, go with either and someone is acceptable US English

Answer 3

The first one is best. I would take the first answerer's suggestion as well. And yes, somebody would make the quote a whole lot more inspiring.

Answer 4

I like the first quote.

Answer 5

Dreams come true one.

I'd say "If anybody" rather than "when someone/somebody"--sounds more positive.
