Idealism in my daily life

Throughout history, many historical figures have pursued ideals that are almost unrealistic. People, like Stalin or Lenin, had an extremely perfect vision of a world, but when they tried to implement it, the results were violence and dictatorship. In George Orwell's Animal Farm, idealism also fails in the end when the pigs basically became humans and broke all the promises that were once promised by Old Major. Obviously, idealism is bad for these leaders who tried to use it in their own "world", but after reading these stories, I realize that I use idealism on a day to day basis and it also causes me a lot of trouble. 

Every week, I make a full schedule for what I will do this week. I have been doing this for a long time and I now have a habit of tightly following every schedule I make. Now this might sound like a good trait to have and I agree. But the thing is the schedules I have made are usually pretty unrealistic. My schedules are based on an ideal world where distractions don't exist, I never get bored of studying, and my hands never get tired from writing. So sometimes my schedules will consist of 5 out of the 7 days doing basically nothing, and the other 2 days are fill with studying and homework. When I made the schedule, everything looked fine and doable, but when I open those books and studying guides, boredom and tiredness starts to kick in. I start browsing youtube and Reddit to look at useless stuff to take my mind off the work I still have. Then when the allocated time is around halfway over, I realize that I messed up and start cramming work. Of course, I still finish everything on time, but saving everything for last minute is usually really stressful and sometimes I accidentally skip over things/instructions that are essential.

P.S. The reason why I think I work better in stressful situations is probably because of this "ideal schedule" I have. So I'm not too mad at myself for doing this almost every week.
