emotion

You overestimate your ability to manage your future moods.

Projection bias is the tendency to assume your future self will have the same tastes, desires, and emotional states as your current self.

You shop for food when hungry and buy too much, or make future plans while feeling happy that you cannot follow through on when feeling low. The brain struggles to simulate future states that differ from your current physical or emotional reality. You treat your present state as a permanent condition.

Your current mood is a poor advisor for your future needs.
