Just learning other peoples stuff = boring.
I disagree here. Strongly.
In order to know what you like, you have to hear it first. In this day and age, little Mozart's hardly exist. They can't write 27 piece orchestra symphonies with a pen and manuscript at a table and not even having an instrument on hand. They just don't come around anymore. So, you have to hear it first, and you hear it by listening, to many different things.
I started out, as an SRV fanatic. Then, I heard his brother, Jimmie. Then Ronnie Earl and Magic Sam. Each time I heard one of these guys, it excited me. I sat down for hours, playing their rhythms, leads and learning the nuances of each persons style as much as I could. What made them play this lick, was it a lick or did they do that instinctively, what made them play that there? Was there a reason...did they play it to connect to another lick, do they think in "licks" or do they just "play?" Joe Pass, though he downplayed how much he would think about it, had to think about what he would do and where. But he played for hours, days, nights and endlessly practicing so he could play what he heard in his head.
But, how do you know what you want to sound like, unless you hear it somewhere else? It might be John Coltrane, the way he runs scales. It may be the sheer power of SRV, or the finesse of Eric Johnson as he integrated all the arpeggios together to make his own style, after he was strongly influenced by Hendrix. Maybe you want to play like Yngwie Malmsteen, who just rips off (very well though, and at a ludicrous volume!) Paganini for days.
But, at the end of the day, in order to make your own style, you have to know what you want to play like, and you do that by hearing the players that inspire you, and then imitating them. We learn to walk, talk, play baseball or many other things in life via imitation.
Why should music be any different?
