How do you know if you made the right choice?

You never know what the right choice is before you make one. You have to think about yourself, but also how you could arrange that with others. You should never leave someone if they are ill, or need help. The least you can do is to ask someone else to do that for you. If you promise someone something, you have to at least haave a true, really good excuse. If you fail a friend on something important, you might never be able to make up for it. If you make the wrong choice, you might never be able to make it up...
