You shouldn’t expect someone else to take care of the things that need to be taken care of. All too often even the most obvious stupid little things get ignored by the members of a community until it becomes an utter tragedy.
The first public community you take part of is your neighborhood. It’s the first level that contains people you are not related to. It is here your should start. Not fixing the world’s issues. Fixing the issues of your community.
You can’t wait for others to do it, as you are a living part of your community body. If you see it, do it. You are one who can come through with a solution to the problem. If you can’t do it alone, ask other members to join you. They will come if someone takes the leader’s position. It’s easy to take orders. I’m sure you would prefer it yourself.
But someone has to take initiative. And it can and should be you, since nobody did anything about it until you’ve become aware of it. A done job is a done job. Who’s to say you’re unfit for a job no one seems to be fit for in their minds?
Make your small world a better world. Then you can move up to higher levels.
