Either speed up irrelevant parts in post-production or generally better, get rid of them.
If you don't feel like having a full-time job as a video editor, turn the camera on at the top and off at the bottom.
Even still, 95% of what you capture will suck and be unwatchable.
If you want to capture your day but not deal with tons of video, does the camera have a timed picture mode? I use this on days where conditions don't really warrant video- I just set it to take a picture every 30 seconds, turn it on, and spend a few minutes at home marking the good pictures.
