"Contentment" seems realistically defined as "enjoyment of whatever may be desired". That definition is realistic because the more contented an individual or community becomes the less extreme so more acceptable their desires will be. Contentment is an intuitive natural concept, whereas "peace" is a civil and so non-intuitive concept dependent on restriction, whereas contentment was and is self sustaining. -Wikipedia
Regret is a negative conscious and emotional reaction to personal past acts and behaviors. Regret is often expressed by the term "sorry." Regret is often felt when someone feels sadness, shame, embarrassment, depression, annoyance or guilt after committing an action or actions that the person later wishes that s/he had not done or having not committed. -Wikipedia
Contentment is somehow related to regret. If a person does not desire for more or accept the things that s/he have, contentment would be achieved but when a person seeks for more than what s/he have, here comes regret. There's no wrong in seeking much better things but if it just make you feel insecure and self pity, well there's something wrong. You regret because if you didn't do this or that in the first place, it would not resulted to what had happened. Regret is an awful thing. All I can say, learn to appreciate whether little or big it may be because you'll never knew that when you think you lost a small one, you already lost a big one.
To all the girls, learn to love the person who is willing to take each and every chance to make you feel happy like you are the only girl in the world and you are his everything, don't compare, learn to appreciate, be showy even for a while and be contented.
