The other day, I found myself standing outside my own house, unable to get through the front door.
Our front door has one of those keypads where you punch in a code, hear a little beep, and the door unlocks. It is incredibly convenient right up until the moment it decides to stop working. I entered the code, pulled on the handle, and nothing happened. I tried it again, assuming I had somehow forgotten the same code I had entered hundreds of times before.
Still nothing.
The batteries inside the keypad had died, which meant I was standing a few feet away from everything I needed with absolutely no way to get to it. My keys, wallet, chargers, clothes, food, and every other modern convenience were sitting safely inside while I stood outside looking like an idiot trying to negotiate with a door.
I quickly realized I had another problem.
I did not have a spare key.
A spare key is one of those things you rarely think about until the exact moment you need one. When the door works, carrying an extra key feels unnecessary. You convince yourself the keypad will always light up, the batteries will always have power, and the code will always let you back inside. The entire system feels dependable until it suddenly is not.
Careers work almost exactly the same way.
Your job is the front door. As long as your badge works, your paycheck arrives, your boss likes you, and the company appears stable, you assume you will always be able to get inside. You become comfortable relying on a single entrance because it has opened every morning for years.

No spam. Just straight-talk career advice, every day.
Then one day, the batteries die.
The company gets acquired. A new leader arrives. Your department is reorganized. The budget disappears. Your position is eliminated. You enter the same code that always worked, pull on the same handle, and realize the door is no longer opening for you.
Most people start looking for a spare key after they are already locked out.
They update their resume after they lose the job. They reach out to their network after they need something. They start thinking about savings after the paychecks stop. They decide to build a personal brand after nobody knows who they are. They explore a side business after their primary source of income has already disappeared.
That is the worst possible time to start making a key.
A strong network is a spare key. Money in the bank is a spare key. A current resume is a spare key. A side business, a professional reputation, a valuable skill, and relationships outside your company are all different ways to make sure one dead keypad does not leave you standing outside in the rain.
None of this means you should spend every day terrified that your career is about to fall apart. You do not need to live with one foot out the door or treat every employer like they are secretly plotting your exit. You simply need to understand that career security does not come from trusting one door to open forever.
It comes from having more than one way inside.
The best time to build your network is when you do not need a job. The best time to save money is when the checks are still arriving. The best time to update your resume is while your accomplishments are fresh. The best time to start experimenting with another source of income is before your current one disappears.
Preparation often feels unnecessary when life is working.
A spare key feels like one more thing to carry until you are locked out. Then it suddenly becomes the most valuable thing you own.
Eventually, I found my way back inside the house, thankfully, due to the emergency USB-C port that was hidden on the keypad. The batteries were replaced, the keypad lit up again, and the door went right back to working as though nothing had happened.
Career security does not come from trusting one door to open forever. It comes from having more than one way inside.
This time, though, I am making sure I have a spare key.
