I don't think it is necessarily a bad thing. I spend a lot of time planning because I find my coding productivity is higher. Often it's better to let problems sit for a bit than to code then first, or if one does a mock-up it is an exploration that is part of the planning, to be discarded and done right a second time. But what this means is I rarely come in the next week and wonder what I was thinking (it does happen, but rarely). More often I look at things, over a few months figure out better solutions to coding problems and my style changes accordingly.
