Contractions are simply two words that are put together using an apostrophe to shorten them.
For the first blank, we use You're. You're is a contraction for the words, you are.
It is different from the "your" because this particular word is a possessive pronoun. It modifies a noun that indicates ownership.
You are your own worst enemy. → You're your own worst enemy.
Another example would be the second line.
They're going to say what they say, but their opinions aren't holding you back.
They're and their are also commonly misused words.
They're is a contraction for the words they are.
Their is a possessive pronoun as well.
Same rules apply when to the other words as well.
