Life can really be fustrating at times in the sense that what we want is not actually what we stand to gain from life at times and that can really be quite frustrating. But well just like you said, life have always been a continuous struggle and we will keep going in it. We will not give up because giving up is never an option
Giving up is not an option and shouldn't be. It takes courage and strength to live in such a world as this and character and strength can be built.
