Including you. That matters, because just because someone can doesn’t mean they will.

A lot of people can do a lot of things now, but most people won’t do more than they have to (if even that!). The barriers: 

Open-mindedness to notice a problem.

Courage to overcome fear. 

A willingness to put effort and energy into an attempt. 

Flexibility to learn, take in feedback, and improve.

Perseverance in the midst of uncertainty and doubt. 

Everybody can tap into these qualities, but most people will not because it takes effort. In that sense, not anybody else can do it; only you at this moment. And if you don’t, there’s a chance it might not get done.
