Galatians 6:9
9 Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up.

The reason why some things to hang on do not want to give up, just do not want life to regret, because well aware of each sound farewell may be a farewell of life. Each sigh might be the last sound of life. Every moment may be goodbye. Some things you nostalgia destined to give up. Life there are many kinds of love, but do not let love become an injury.

No matter what you're going through, there's a light at the end of the tunnel and it may seem hard to get to it but you can do it and just keep working towards it and you'll find the positive side of things.
