you just have to have discipline and rememeber that it pays off if you keep at it.
you can improve your playing by practicing 30 minutes with a metronome exponentially better than you can without one.
if your going for the steve vai, satch, dimiola, satch, yngwie, impeliterri, morse,petrucci etc type of playing a drum machine or metronome, even a wris****ch, is essential. read interviews with these guys and they will say thesame thing.
just don't let that be the only thing you practice with a metronome...practice your songs and everything else with a beat of some type. its all about developing your rhythm not only your leads. 90% of your playing is rhythm.
but all that is about "practicing" not playing...which is when you turn off the metronome and just wail and rock out.
