A second marriage is not necessarily a compromise or sacrifice. A second marriage is a good thing, it shows that an individual has been able to move pass the first marriage. Remember your happiness is the most important thing.
If you find love again, second marriage is a good thing, mistakes from the first marriage will be avoided and lessons learnt will be implemented to make the second marriage better.
If you go into a second marriage as a compromise or as a sacrifice (many because of your children) you might end up being disappointed and the second marriage might be more disastrous. Your happiness is the most important thing to watch out for, if you are happy with your new partner, a second marriage is not a bad idea.
A second marriage can be a good thing for you. It is neither a sacrifice nor a compromise. You can actually learn from your past mistakes and work on yourself, before finding someone that truly loves you for what you are. You also learn from your past mistakes so that you are able to nurture this relation better.
A second marriage can be the best thing that ever happened to you. However, if you opt for it as a compromise over sacrifice for the sake of your children or the community, it may end up just as disastrous as the first one.
