I believe that working from home is a great thing and can be much more productive and profitable than moving and going to work elsewhere.
Obviously, as you wrote, there are many factors that come into play.
The amount as in everything in life, I think is knowing how to manage.
You're right, working from home might be profitable because you don't deal with stress and don't spend dime moving around. But if you're introvert you will not enjoy working from home.
Yes, I agree as we said, it depends a lot on the characters of the people, there are many things to evaluate.
Yes it depends my friend
