Pepsi isn't the only popular soda. Just like Nike isn't the only popular shoe brand. You're not the only (insert your profession) unless you are; and they're going to do it as well, if someone thinks they can do it and be profitable. Some folks needlessly worry about others' so-called flexing on social media. I'd rather be happy with them and get close enough to learn something new. If you have an issue with others' success then I recommend you follow King Solomon's sage warning about vanity, as there's, '...Nothing new under the sun...' unless it's your new attitude.
