In some cases it makes sense to go out in the world in person and expose yourself. A professional that visits a trade show, for instance, is doing just that. A promoter that visits a nightclub and introduces himself to people is doing the same. A book author showing up for a book signing is doing the same.

Just make sure that, when choosing an event to participate, that you take into consideration all the costs, financial and otherwise, and compare them to the option of sticking to your online game.

At what places you should be showing up?

Only those places that are focused on the specific area of interest of yours, where people gather to socialize and/or make business, where you can learn from others and/or give them value by teaching them something.
