Although it is tough for an individual to find what they click with, it's even harder for a third party. So the only advice people can give you really IS "just try things until you find what works for you". I mean, it's doubtful that if you forced a person to try something new, they try something that they know they will absolutely hate.
Also, "Be a rockstar" is not a smart goal to pursue (in that it has a high probability of failure), but playing an instrument with some level of mastery is. If you base your satisfaction on goals with a strong degree of randomness or innate ability to their achievement, you will probably be unsatisfied. Better to base goals on things you can (almost) fully control.
