Having revenge on someone or something is not good for yourself and your karma.
Yes, karma is real,
When someone looks down upon you or belittles you when you when you express your dreams, or an idea to create something or do something with your life, don't argue with them. Just stay quiet as much as it may bother you don't respond back, they just want arise from you. Instead, show them off by your actions and constant actions of working towards your goals no matter how many are hating you for it.
I'm not that big of a fan of Beyonce...
I know, I know shocking and I probably just lost some of your interest in saying that.
But it's true, I'm not a complete and uber fan, doesn't mean I don't completely dislike her, but her song "Formation" is probably one of her better songs since "Baby Boy" (in my opinion, remember, everyone is entitled to their own opinion).
But in Formation she talks about haters and how they're corny spreading rumors about her, how her Southern roots influence her, but most importantly, the very last line in the song is "always stay gracious, best revenge is your paper."
What an awesome line that is...
Best revenage to your haters is your paper, you don't have to let them know what you're doing just by showing them your results is enough to make them shut up for eternity... or just long enough for them to realize they were wrong and feel like complete asses about themselves... or even ask you if they can join you.
Next time someone down plays your ability for anything you want to do whether it's money related or an advance in your lifestyle, don't tell them about it, you can if you want to test your friendship with that person, if they will support you through it or think your just plain stupid, but rather put your words into action and show them. It's like the saying, "talk less, do more." Don't talk about it, be about it.
You can do anything you want, but always remember when you get there humility is key.
