People give up because they felt unaccomplished. They felt they are being unrecognized or unappreciated. Because people themselves are their own expectations. You are your own judgement. We have to do this and that to feel secure, accomplished, completed and praised. But we didn't think how much we push ourselves that it is already our limit.
And that's when we cry. Crying makes your heart feel better. Every year represent something in your heart. Crying makes you feel better. All those guilt, hurt are all gone after the crying.
It's okay to feel sad but not all the time. Take that time to reflect what made you give up and ask yourself, what should I do more?
