Absolutely, I work with blocks that only vaguely direct me with working on things I need to. With iOS calendar on Mac and phone it’s also easy to flip things around as you go. I just have an X amount of time in my week outside of my varying weekly study schedule so I plug things in and allocate with a lot of buffers in-between to not be too tight. It’s important to not be too harsh on yourself if you didn’t manage to do something. Just move it over to next week free block and re-adjust it on your next planning session on Sunday. If it is something extra important with a deadline, mark it with a couple of exclamation marks. You can then at the end of week also review your progress with your longer-term goals. Voila! Works!
