Start from the end. The answer often reveals the path.
Chemistry: retrosynthesis works from the final molecule back to cheap starting materials.
Psychology: don't chase happiness; delete what reliably makes you miserable.
Computer Science: assume failure first, then trace the break.
Problem-Solving: picture the winning end, then reverse-engineer the moves.
Munger: know where you're going to die, and never go there.
Habits: don't design the perfect day. Remove phone, junk, friction.
Everyone races forward toward success. The sharp ones start at the outcome and walk back.
