EVE definitely rewards goal-setting. Once upon a time, I think they had 30 day trials, which, IMO, was a much better program.
Most people that I know in EVE didn't buy it on their first 14 day trial. They bought it after their second 14 day trial. The first 14 days is spent figuring out what the hell everyuthing is and how the game works, as it's so alien when compared to your typical, "Look, I'm a warrior, and I'm going to save your village, just like everyone else has done before," MMO. The skill system, the fitting system, the actual market, and the meta are all things that need to be understood before you can really scratch that itch.
Hopefully you come back. Set a goal for yourself: What do you want to accomplish? Do you want to be space-rich? Blow up other people's ships? Explore the new sites that are everywhere now (I expect them to scale back the spawn rate sometime soon...)?
If nothing else, EVE also has a great community of dedicated, helpful people. Even some of the biggest jerks in game are people I'd gladly share a pint with in real life; and in many cases, have.
