sometimes when you get rejected for something or things just didn't work out, you may wonder if you could have done more? is it because you didn't do enough? is it because they don't like you? you may feel so bad that you might start to feel discouraged and depressed. Keep your chin up, when something doesn't work out it simply means that something better is coming. stay positive, you will succeed if you keep working hard.
There's more to come, believe it.
