Q&A: How to ensure time blocking works for your personal business tasks

I have a question about time-blocking as I heard you talk about it many times but I’m still struggling with it! So I use Google Calendar and I love it. I schedule all my appointments there, and I don’t have any problem showing up for them but when I schedule tasks I struggle to respect the commitment. I don’t have kids or a relationship at the moment so in a certain way I have lots of time to use. I enjoy this spaciousness and couldn’t function with a full schedule, but at the same time I often manage to skip that time I blocked because in the moment I may feel tired etc. What’s your advice?
