For me it´s the internet!
Reading, researching, watching videos, sometimes music videos, writing for steemit, the days just fly by and I have done not much else on a typical day, since I discovered steemit last July. For about 3.5 years I´ve done pretty much every day what I wanted and since I´m scared stiff of work, work was not part of it.
Reading is definitely a good one for me. Talking to people for hours on end is another. Oh, and traveling. That's probably my favorite game. Can't believe I didn't think of that one.
