1. If you are in a product company, often you get into this weird habit of talking endlessly about technologies and some new cool stuff coming out.

Actually, sometimes it reduces the strain of heavy thiking/coding.

However, the discussion very soon digresses to a number of other topics.

Need to just focus. If someone talks, give a smile and back to screen.

2. If you are sitting late night (as always :-)), then perhaps online activity can be reduced a bit; like checking news tools, trends, analysis, blogs etc.

However, on this part I am still struggling.
