@bking: I am glad you asked this question. I do exactly what you say: After my regular 9-5 job, I work another 6 hours on my personal projects & I have been asking myself how to increase efficiency in those 6 hours (because my personal projects really matter to me the most). Recently, I have come up with a model whereby, I work 6 hours after work, every alternate day. So, I'd do my 6 hours on Monday, and then take a break on Tuesday after work - Id spend around 3 hours improving what I did on Monday (so, "no innovation" day). Those 3 hours actually help a lot - I try and read docs/SoF, watch some stupid tv, spend time with my gf and off to bed. I repeat this pattern every alternate days. To be honest, this model seems to work. Thats my 2 cents.
