God wants us to live like the grass. Even if it's stepped on, crushed, burned and cut; it always persists and grows back even greener and stronger.
In our lives sometimes we fall short of overcoming challenges. Losing a battle in life is a hard circumstance to stomach, especially if a lot of hard work and care is what you put into something. There are a few things to remember about getting back up, and being persistent, one is that all your hard work from before will really go to waste if you just quit trying all together. Second of all, you don't want to be remembered as or remember yourself as a quitter, and wonder for the rest of your life on what could have been. More than likely what you need to accomplish is something that someone else has accomplished so it's not impossible to do. Even if your feat has never been accomplished, that is all the more reason to try again, and try even harder to do something and be remembered for doing it.
