You've watched 90 minutes of a terrible movie. Should you finish the remaining 30 minutes?

You've avoided the SUNK COST FALLACY!

🔑 Key insight: The 90 minutes are GONE regardless of what you do now.

✅ The right question: "What's the best use of my NEXT 30 minutes?"

Past investment should not dictate future choices.

A SUNK COST is any past investment that CANNOT be recovered:

• Time already spent

• Money already paid

• Effort already expended

These are gone forever—the only rational question is what to do NEXT.

Sunk cost fallacy traps us everywhere:

• "I paid for this food!" (but eating when full costs health)

• "I invested 3 years in this relationship!"

• "We've spent ₹50 lakh on this project!"

Past investment shouldn't dictate future choices!

Ask yourself:

"If I were starting fresh RIGHT NOW, would I choose this?"

• If YES → continue

• If NO → quit, regardless of past investment

Quitting isn't failure—continuing despite evidence IS!

Fair—but here's the key:

❌ Wrong factor: "I've already invested 90 minutes"

✅ Right factors: Will the next 30 minutes be enjoyable? Informative? Worth your time?

The past investment should have ZERO weight in your decision.

SUNK COST FALLACY: Continuing because of past investment, even when quitting would be better.

• "I've come this far!"

• "I can't waste what I put in!"

But the waste already happened! Continuing just adds MORE waste.

The fallacy appears everywhere:

• Finishing food you don't want ("I paid for it!")

• Staying in bad relationships ("I invested years!")

• Continuing failing projects ("We've spent millions!")

• Reading boring books to the end

Instead of "How can I quit after investing so much?"

Ask: "If I were starting fresh RIGHT NOW, would I choose this?"

If you wouldn't START watching this movie now, you shouldn't continue!

Why do you feel you should finish?

🤔 If it's: "Because I already spent 90 minutes"—that's the SUNK COST FALLACY!

✅ If it's: "Because the ending might be great"—that's a forward-looking reason (valid!).

The key is: Are you looking backward or forward?

A SUNK COST is any past investment you CANNOT recover:

• Those 90 minutes are GONE whether you stay or leave

• You can't get them back by finishing

• Continuing doesn't "honor" the investment—it just adds more time

This thinking trap appears everywhere:

• "I paid for this food!" (so I'll eat even when full)

• "I've been dating them 3 years!" (so I'll stay even though unhappy)

• "We spent millions on this project!" (so we'll keep funding it)

Past investment pulling you forward = fallacy.

Instead of: "I can't quit after 90 minutes!"

Ask: "If I were starting fresh RIGHT NOW, would I choose to watch 30 more minutes of this?"

If NO → walk away. The past investment is irrelevant to the BEST decision NOW.
