Honoring My Calendar

I am working on Monday Hour One and I find that my current thinking has allowed me to not honor my calendar. I found some thoughts like “It doesn’t matter” or “I have time” or “I should do X instead.” I know that being able to put something on my calendar and honor it no matter what is the key to my dreams. What are some specific baby steps I can take to get out of my pattern? A typical scenario for me is putting more things on it than will fit realistically and then not achieving half of them. Thank you!!!
