I have been working remotely for past few month - it is the most difficult thing in my entire career.
The point you have mentioned it very valid - one should be properly dressed before the meeting and before the work - because it adds to your performance
I have noticed that when I work in my night suite I m more lazy but if I shower and change my dress - I am. more active.
I suppose that it depends on your preferences, personally I find not having to commute or dressing up to be very refreshing, as I can perform my job very well regardless of what I'm wearing when I am working, but I can understand why some people may not like this and could prefer to dress up and follow the same routine they have followed for years on their regular job, even if it isn't absolutely necessary since they are working from home.
The stress and the hassle on getting up on bed early and make those usual routine specially on daily commute is really gone when you do work remotely and thats the beauty of it which it cant really be
that stressful on your part but in exchange which you do work on a space where you are just the only one on that certain place or on your bedroom which other people find out to be that too boring
on doing such thing which i couldnt really blame them on because there are really times which we do really love to socialize and interact with other people thats why they do really prefer on going into
certain job sites and do able to see and feel the ambiance with other people but since there are ones who are lonely types or just love to work solo then its up to your choice.
We do have different preference and interest in life.
