Many of these were good… I just wonder by what verifiable sources you concluded them. Some I disagree with or only partly agree with as they seem very self-absorbed… are these really what most regret one day? I don’t think living without regrets means only doing what you want. Here are a few suggestions: Not giving more to charity; not encouraging others more; not realizing what I don’t need to be happy, etc. Some more: not having more kids; not letting her/him walk away that easy; Not learning to give up on failing projects.
