it's best to Treat a choice as incapable of being changed or undone (even if it technically is)
A strict decision-making technique which encourages people to “cancel out" the opportunity of swapping out a decision made for a different one. Much like having an option of returning a product to the store or exchanging it for something else, the mere idea that we have this option available, even if only in the distant future, causes us to constantly suffer. We question the choice we made and whether or not it was the right one; we experience ongoing feelings of regret, agonizing for days or weeks at a time about the option to undo our selected choice, only to ultimately do exactly that. But by finalizing our decision completely, we actively force ourselves to feel whole, moving forward without second-guessing our choices or occupying our minds with questions and regret.
