Depends on the work I need to do. In some instances, I need the peace and quiet only my home can offer, other times I feel like getting dressed, going to the office and sitting down at my desk helps me get into the proper mindset.
im an office kinda guy... but i certainly would love for my office to be near to my residence as far as possible... which is not the case right now... the city trafic takes the living day lights out of me... i hate the commute to office...
