Pushing clouds with chopsticks

Perhaps if I hadn't had a previous career outside of software it wouldn't bug me so much, but I find the nebulous, amorphous task of software development thoroughly frustrating. It was back around 2003 that I was having a conversation about a project with my project manager at the time (who was old-school yet awesome), and I told her, "It's really like trying to push a big cloud and all I have are two chopsticks." I'm closing out my 13th or 14th year in software development, and I still feel this way. Even with all the insight, feedback, and visibility into a project that Agile Software Development provides me (and yes, real Agile, before anyone bothers to say that I feel this way only because I'm not doing full Agile Software Development), I'm still frustrated by how unwieldy the whole practice can be.
