I suppose it depends on what you're trying to be. Let's take the change of making society (your town, country or civilization) better. To be that change you have to try being a better person. Work on your character and health. Get involved in your local community. Inspire others to care about the community like you do. Something like that.

Refuse to compromise. Refuse to pass your responsibility to someone else. Refuse to appease people out of reflexive empathy.

You can do something that you think someone else has to do or can do. Or just change your outfit. u know

Do this at work and some managers will freak out because you didn't include them even if whatever you did improved something greatly since they can't steal the credit by saying ok.

Step up and take the labor on your own. Don't brag about it just do it . I tried that. I was a custodian and went into a department and started wiping down stuff when I had some time. I was told to stop by a manager because it was the sales peoples jobs even though they use minimal staffing so they barely have enough time to stock, helping out and cleaning was something they didn't want me to do even though I was a custodian/maintenance.
