A Shark In My Tank

The Shark in the Tank: Why Challenges Keep Us Alive

I’ve just returned from a trip to Asia, where I came across a fascinating story about Japanese fishermen — one that carries a powerful life lesson.

For generations, the Japanese have loved fresh fish. But as nearby waters became scarce, fishermen were forced to venture farther out to sea. Bigger boats, longer trips — yet there was one problem: by the time the catch returned, the fish had lost their freshness.

At first, they tried freezers. Practical, yes — but the Japanese could taste the difference, and frozen fish weren’t welcome at the table. Then came live tanks. The fishermen caught the fish and kept them alive on the journey back. But after days of swimming idly, the fish grew dull and lifeless. Again, the taste wasn’t the same.

So, what was the solution?

Here’s where the story takes a turn. The fishermen introduced a small shark into each tank. Of course, a few fish didn’t survive, but the rest kept moving, fighting to stay alive. By the time they reached shore, the fish were lively, energetic — and tasted as fresh as if they had just been caught.

Now, here’s the truth behind the metaphor:
We are no different from those fish. The moment we stop moving, stop striving, and settle in comfort, we lose our spark. Challenges — our “sharks” — keep us alive, engaged, and growing.

So don’t fear the problems in your life. Welcome them. Each obstacle is proof that you’re alive and moving forward.

If you’ve achieved your personal goals, don’t stop there — set bigger ones. Expand your vision beyond yourself: to your family, your community, even to humanity. Success is not a place to rest; it’s a platform to rise higher.

Remember: the shark in your tank is not your enemy. It is the reason you stay fresh, strong, and unstoppable.

So ask yourself today — what shark do I need in my tank?
