Meaning, whatever problems life has offered, don't make it stop you in achieving your greatest dream and future. Just fight the challenges with dignity, determination and bravery. Just keep on fighting for life and don't let the challenges and problems be a hindrance to your success!

This simply means that when someone brings you down, get back up. If you really want to achieve your goal in school, or in life (or whatever), just give your all. Don't let anything stop you with just one blow. Mind you, this doesn't always mean you get "exactly" what you want.Remember, life may be unfair, and sometimes even your best is not enough. But keep trying. Don't give up. These challenges and obstacles are what will make you strong in the end. If things go badly for you, remember: Sometimes, the people with the worst past have the best future.
