If you are deeply concerned and consumed by world events, or even just local ones, step back and analyze it. Too many thoughts mean too disorganized without a real goal - find your focus. Maybe you have the time and resources to take on the world – great! Most people can’t - don't take on the world. For them – don’t stress as there will be more time later to tackle things.
Do you want to make a difference? Do you have time to step out of your life to do it (is a job holding you from being able to have time to deal with it)? Big decisions might have to be made. Focus on what is most important.
Baby steps to start – make a plan and a list of what needs to be done and how realistically you can schedule tasks in. Start at the local level and work up. Only do what you can in the amount of time you have – job and family are perhaps a bigger priority.
Maybe you are wanting to help with climate change, with COVID response, with mental health, with shut-ins, with government, with battling illnesses, etc. Pick ONE cause to go after – don’t dilute yourself to try to take on several – you will fail at some or all.
Figure out the contacts you need to talk to and start making calls. In talking to people, you can get more information, more names, and more task ideas. You might even get derailed into a different path or even a different aspect when you get a clearer understanding.
Study up on the topic – dig deep on reputable websites like https://scholar.google.com/ - where more unbiased facts are presented. Keep grounded from opinions that try to sway your thinking. You might even want to take a class to get better informed.
Start making noise – post on social media, write articles, do podcasts – make sure people get informed about your cause. Get people to follow and help you. Maybe you need to raise funds – ask for donations or crowdfunding where appropriate.
Just take on what you can in the amount of time you have available. Don’t overdo your time and take away from your other commitments. Be proud each time your check off a task as done. You may make an impact in the world (but don’t try to take on the world – just steps), or maybe just in your community – either way it’s a win and accomplishment! One step at a time.
