What if time blocking doesn't work?

I recorded a video about my view of productivity where I talked about how chunking work and giving yourself a fixed amount of time can be a nice way for me at least to stay motivated and get more done. But Stephanie asked on the video, you know what happens if you don't get enough work done in that fixed time slot? Do you add more time? Do you just feel bad and beat yourself up? In my view, we need to be okay with that. I think that's where having a buffer and a process in place, certainly surrounding your work chunks is going to help you. Yes, it's easy to just feel bad or to say, oh, I need to stay late to fix this. And maybe in some cases you do. But if the system itself is set up so that you always have a five week buffer, a four week buffer of YouTube content, well then you don't have to put so much weight into each specific chunk. You don't achieve the outcome in a given chunk of time, adjust those expectations or add a little fire under your butt for the next two hour chunk. The next week.
