One of the biggest challenges you will face in your career is not KPIs and deliverables or project timelines or stressful days and nights. It's working with people. Specifically, it's working with the same cast of characters that show up in every single office, regardless of the industry, the company size, or the city.

Every office has them. Once you learn to recognize them, you can stop being surprised and start being strategic.

The Politician. This person is more concerned with how they look than what they produce. They're in every meeting, they know everyone's name, and they have a talent for taking credit without doing the work. The key with the politician is documentation. Know what you contributed and make sure the right people know too.

The Coaster. They've been there long enough to know exactly how little they can do and still keep their job. They're not malicious, just checked out. Don't let their energy drag yours down and don't carry their weight — that only rewards the behavior.

The Emotional Basketcase. Every interaction is a production. Small problems become catastrophes. Drama follows them like a shadow. Keep your interactions professional, short, and documented. Don't get pulled into their narrative.

The Hardheaded One. They've decided how things should be done and no amount of data, logic, or evidence will change their mind. Pick your battles. You won't win every argument, but you can influence outcomes by framing things in terms of what they care about most.

The One Who Actually Gets It Done. This is the person you want to be and the person you want to be around. They're not always the loudest in the room, but they're the one people go to when something actually matters. Align yourself with them whenever possible.

The mistake most people make is spending too much energy trying to change the characters around them. You won't change them. What you can control is how you respond, how you protect your own output, and how you position yourself relative to all of them.

The career that wins is usually the one that figures out how to navigate the full cast without becoming one of the bad characters themselves.
