1) My productivity seems to be polarizing. In some day I feel I have accomplished a lot more, but in other days not great. Generally, many things seem to take longer to attain.
2) My working environment simply sucks. I only have cluttered desk with my personal equipment. I improvised the TV to use as my secondary monitor, but is definitely not optimal from ergonomic standpoint, so mostly ended up working on the tiny laptop screen. I upgrade to better chair, and that at least helped me a lot.
3) I don't have air conditioning, and if the WFH prolongs, this will be problematic.
4) My workout level certainly has dropped for a while after the lockdown WFH started. I have gradually improved this, by establishing daily walking, and remote work out sessions.
