Sometimes, we find ourselves in situations where we’re debating whether or not to carry something with us. Should we take a cap or that extra bottle of water when it doesn’t feel like it’ll be needed?
If you’re debating whether to take something with you and the cost of carrying it is low, the optimal decision is to simply take it with you.
If you don’t end up needing it, the cost was low anyway.
And if you do, you can now feel great about your decision making and skip cursing yourself for not acting on an impulse.
