I think this biggest challenge with the pandemic is that your home became the space for everything, not just work.

Before the pandemic, if I felt like I needed a change of space I could go work at a coffee shop or I was able to go to the gym. Once everything closed home became the space for everything, but for myself and my partner. This made it really challenging to have boundaries around work and leisure time.

I think right now remote work can be especially challenging if you don't have your own personal workspace, but that's obviously a luxury that may not be available for everyone. This may not have been as noticeable before but with more people/family at home the problem is amplified
