For the love of all that's sacred and holy, STOP before you hurt yourself.
A lone fuck, separated from the herd, has wriggled its way out of your codpiece and is making a break for freedom. People whose opinions don't matter are clustering nearby, mooing eagerly in the hope that you will offer it up. With bated breath and slavering tongues they await the presentation of the glorious genital benediction that's close enough for them to smell.
You're one pelvic thrust away from doom. DOOM!
All it's going to take is one twitch of your groin, or possibly even a routine public adjustment of your underwear, and your self-worth will forever be determined by the random mental and verbal spasms of cretins. But why?! They don't yet understand cause and effect. They're mercifully beyond the larval, squalling state but they're just as immature as pupae are. Yet unlike the pupa, some of these co-workers will never actually mature into an adult worker bee, much less a queen. Why, therefore, should you let the opinions of these lesser beings be a blip on your radar screen, except to the extent it benefits you financially?
They're going to judge you to their wills' satisfaction, of course, and not all of them will keep the verdicts to themselves, but that's normal human nature. The thing that's making you feel isolated is not them. It's you.
Let it therefore be written: uneasy lies the head that wears the crown, but most easy lies the head that wears the 'stache. But either way, like the king, the queen, or the proverbial cheese, you're going to stand alone for a while. That doesn't mean you need to be lonely.
You may, if you wish, provide subtle leadership. Allow pearls of wisdom to occasionally drop before your co-workers, in the hope that they learn the merits of index funds and cleave closely to the Vanguard investments, rejecting the demon of day-trading stupidity, and embracing the wisdom of maxing out every 401(k) and Roth option in sight. But do not invest too much of your hope in their response lest your wayward swive make another appearance and get you into trouble.
At the moment, you have to understand that your co-workers thirst less for your investment wisdom than they do for the fornication donation they sense you're about to make. The latter will give them an immediate sense of power and social superiority over you (which is stupid, from your perspective). Although the former will give them a sense of power and social superiority over most of the hardships that come their way later, it's a long-term benefit. So a lot of them are going to go for the quick gain and the low-hanging fruit. And the low-hanging fucks, if you're careless enough to leave them unattended when draping them over a branch to dry out on laundry day.
Deprived of your fucks, at least some of your co-workers will eventually start to notice the absence and wonder about it. Eventually some of them will ask why you're so happy and mellow all the time, and then you can fill them in about frugality, money management, and FIRE. Then, surprise!-- you will no longer be isolated, because there will be others of your kind.
In the meantime, catch that wayward boff, and put it back in its place. And don't forget to stay thirsty, my friend.
