Upgrade Jitters

[mr_alberta]

Anyone ever have "cold feet" when upgrading their tanks? I have that right now. I would like to upgrade over the next couple of month and am slowly working on getting everything I need together. However, I look at my tank now and say to myself, "oh thats filling in nicely there" or "ooh, look at that growth!" and I question myself as to why I would want to disturb a seemingly healthy system for another one.

I'm sure I'm not the only one to think about this, so my question is, how did you convince yourself to do it in the end?
