Feeling Sluggish

I think I need to have songwriting practice.  Can that be such a thing?  I feel like all I would do is go over scales, but I do that anyway.  I guess I could play my scales more randomly.  That would accomplish something.  I don't think that I would, or even should do songwriting practice every day.  Maybe like once a week?  It should be fairly regular.  People can't just rely on random chance to write songs, can they?  I'm not sure if I can do that.  I mean, obviously I can do that and so far that's pretty much how all of my songs have been written.  Yet, right now I feel oddly compelled to write more songs and yet I have no material.  I don't even have a way to try and make material.  I'm not really sure what this means, but I feel like it's something that I should at least be capable of doing.  Maybe my songwriting practice should be just me sitting with my bass for a while and seeing what happens.  I'll have to experiment more.
