Does anyone else ever have moments of self-doubt, where you just hang your head in shame and feel as though you're the last person on the planet who should be playing bass? Occasions where you're spanking your plank and everything coming out of it just sounds hackneyed, tired, and mindnumbingly dull? I hit that brick wall recently and was wondering how the rest of you deal with it. What inspires you to keep playing after you've vowed to take an axe TO your axe? Any ideas for practice regimens for breaking out of a rut?
