You never know what might have happened... if you had come to the aid of your comrades sooner in battle, if you had confessed your tender feelings instead of hiding them, if you had built your estate a little earlier... Still, there's no point in regretting what didn't happen. Don't waste your time on quarrels, grievances, or sadness. Time doesn't wait, but it works for you, allowing you to gain experience, improve skills, or rest with your battle companions.
