📚 Understanding Opportunity Cost vs. Sunk Cost
In the world of investments, it's crucial to distinguish between opportunity cost and sunk cost. Confusing the two can lead to poor decision-making. Let's dive into each concept and then compare them side-by-side.

💰 Definition of Opportunity Cost
Opportunity cost represents the potential benefits you miss out on when choosing one alternative over another. It's the value of the next best alternative that you forgo.

🧭 It's a forward-looking concept, focusing on future possibilities.
 🌱 It's about the potential gains you could have realized from a different choice.
 📈 It's highly relevant for decision-making, as it helps evaluate trade-offs.

💸 Definition of Sunk Cost
Sunk cost refers to money or resources already spent that cannot be recovered. These costs should not influence future decisions because they are in the past and irreversible.

🔙 It's a backward-looking concept, dealing with past expenditures.
 📉 It's about irretrievable expenses.
 🛑 It should be irrelevant for future decisions, as you can't change the past.
