Each of us can do so much to help the world we're in. It can be in a physical way like helping someone in some way, or being a good friend etc.
Or it can be spiritual like learning (for growth), Or us Jews lighting Shabbos candles before sun-down and other mitzvos, which brings positive spiritual energy.
We especially need to do all we can to help nowadays. - Every mitzvah helps, both between people like tzedaka or improving our character traits. And between person and G-d, like praying, keeping Shabbos and other mitzvos. What we do can make a difference and we can help to make a good impact
We should remember to keep looking towards the light down the road
