So as I was thinking about why my ability to write remains constant and is not particularly seasonal (it is only seasonal is so much that I may have 'seasons' with more time devote to it - rather than ever being unable to write a song) - and here are a few things which I think help me 'keep the tap dripping' in regards to writing songs:
A lot of Scripture & a lot of prayer: the more I read the Bible and the more I pray the more songs I have to sing. And that really is as simple as it sounds...
Devour what inspires you: I listen to a lot of new music; I read a lot of books; I read a lot of comics; I watch TV and Film that inspires me - when you cram all that creativity in often it wants to get out again!
Write for writing's sake: When I was co-writing once in the middle of writing the song the other person was getting a little frustrated that I wasn't bothered that the song wouldn't be that easy to sing in church - they said "It's not a painting to hang on my wall". I've since thought about it and I now think I should have replied "No, it hangs on Jesus' wall". I write because I like it. I write because I want to. Whether or not I choose to sing them at church, is frankly, up to me.
Invest: Time & money. We all wish we had more of them. There will always be more important things to spend it on. Always more noble ways of using your resources. But I find value in creativity; value in being inspired; value in wasting time writing songs. It's a different kind of stewardship.
hope all these posts have helped
