Maybe not directly related to the original question, but what I find is that you have to let your system evolves as time passes. Don't hold on to something that doesn't work anymore, and also don't be afraid to have different ways to approach different aspects of your life (I like to have one system, in my case OF, for everything, but how I deal with finance vs work vs family vs hobby is not identical).

Generally putting projects on hold or in the future helps me a lot as other mentioned. Personally I love having a "someday / maybe" (or even "defenitely not!") folder of some sort.
