What is the difference between Strategy, Plan, and Tactics?

A very short read with examples about using LEGO bricks.

There is a huge difference between a strategy with a vision vs. an action plan vs. a tactic.

I am often given the context of building a long-term strategic plan with healthy and steady outcomes. What I actually find interesting is that most people do not know the difference between the 3 of them: strategy, plan, and tactics.
