You simply cannot be content and regretful at the same time. Regret is the most private feeling or emotion we own. Nobody really wants to air all of their dirty laundry, right? Deep down, we all have a lockbox full of those cringeworthy decisions. Decisions that, when replayed in our minds, can stop us in our tracks.
