Welcome to the dark art of social manipulation. You get a thick, big and strong erection when you see a naked women. Likewise, you can get popular if you push people's emotional buttons just right. When you get people to like you, you get free drinks, easy job promotions and more dates.
The social game is strategic. Unfortunately nobody taught you this in school; you learned by trial and error. The popular kids in high school "gets it". In the working world, those with better social skills will get better jobs and easier promotions even if they're below average skilled, ie the scheming Jew becomes the CEO through social connections or the incompetent secretary who got the promotion by sucking over 9000 dicks.
Here are the strategies you want to follow.
1. Show, don't tell. Never brag about your accomplishments or drop names. Instead, let people see your accomplishments on Linkin or your vacation pictures on Instagram. People are noisy, voyeuristic creatures who love snooping - that's why the best selling magazines of all times are celebrity gossip magazines. People are more infinitely more impressed when they "spied" on your vacation via Instagram than you outright bragging about your vacation. Better yet, let others brag about your vacation.
2. Praise people. How do you come across as sincere even if you have seething contempt for them? Praise occasionally. "Nice haircut! Did you lose weight? You look good today etc." Some people fall into the trap and overly praise which makes the compliment seem insincere. You'll get an intuitive feel when to praise without crossing the line. Praise everyone, even the obnoxious cunt at the office - you want her to be on your side? Why? Because even plebs in numbers can wield power, ie fat tumblrsettes and keyboard social justice warriors. When you help the weak, old and young, people will immediately like you. Politicians know this, hence kissing the baby on every televised election.
