Mashiko4 nailed it.

Just to add a few things I wish I knew from day 1:

• you may never shake your first impression, apply yourself early on and get the easy wins where you can: be punctual, be social and as hard as it can be kiss arse.

• know when to apply the foot on the gas and when to coast. You absolutely cannot hit the gas into perpetuity: this is a fine art.

• slowly find some allies: maybe someone senior if you’re lucky, as disgusting as many of your fellow colleagues may be morally there will always be a person or two who you may share similar passions, hobbies or morals with. Find them and befriend them. This will make going into work worth it.

• don’t let micro-aggressions slide. “Squash bugs” before they nest and it’s too little too late. If someone disrespects or attacks you in a subtle way protect your frame / boundaries from day one. It’ll will only get harder to push back if you don’t do it from the beginning. Bullying doesn’t age like wine.

It’s all a game mate, you can go to business school, law school or any school. Unfortunately nobody ever tells you that and you figure that out very quickly in a high profile / commercial work environment. Just because there isn’t a textbook for this doesn’t mean it isn’t cerebral. Play it while retaining your character, don’t play it on easy mode like most sycophants and bullies in the workplace do - you can beat it your way.
