I imagine that guitars call people for many different reasons. Some might see it as a way to reach fame and fortune. Someone else might see it as way to increase their social status. Whatever your reason, rest assured, it will probably be be quite strong and last your entire life. The best way to approach the guitar is to just pick it up and start playing. Play it as much as possible. It will get easier the more that you pick it up and experiment.
You bought a guitar, what now?
