A great way to keep the momentum going and help bring about change in your community is to join a local environmental group. This should not be a burden to your already long to-do list, but rather a chance to reenergize and explore fun ways to connect with like minded people.
A few suggestions are to look up your local chapter of the Sierra Club. You can get involved in their hikes and outings, or maybe volunteer to be a part of an adopt the stream program or a local campaign.
Another fun organization is greendrinks.org. It's basically a happy hour for people who LOVE to talk about sustaniability and other environmental issues.
