Generally, if you want to go outside of your comfort zone, you might as well do something useful (either for yourself, or for others).
For example, if you try “rejection therapy” (approaching random people, getting rejected, and thus teaching your System 1 that being rejected doesn’t actually hurt you), you could approach people with something specific, like giving them fliers, or trying to sell something. You may make some money as a side effect, and in addition to expanding your comfort zone also get some potentially useful job experience. If you travel across difficult terrain, you could also transport some cargo and get paid for it. If you volunteer for an organization, you will get some advice and support (the goal is to do something unusual and uncomfortable, not to optimize for failure), and you will get interesting contacts (your LinkedIn profile will be like: “endorsed for skills: C++, object-oriented development, brain surgery, fire extinguishing, assassination, cooking for homeless”).
You could start by obtaining a list of non-governmental organizations in your neighborhood, calling them, and asking whether they need a temporary volunteer. (Depending on your current comfort zone, this first step may already be outside of it.)
