Sounds akward but really efective to a possitive result.

Keep the goals to yourself. When you open your mouth and tell your dreams to someone, this person might think:

“this is impossible” or even “he/she is not able to do that” or even “this will be hard to achieve”

If the person you tell is a friend he might say “oh really, that is nice” or if you tell someone not so close to you, he might say the same. Which one is saying the truth, or even what they really think about it; There is huge possibiity this will be untruth words.
