Does anyone on The Misc utilize DAY PLANNING?

I'm talking about planning your day, hour by hour. Even planning for free time. I feel like so much of the time, I am wasting time, thinking randomly and aimlessly, not really focused on what I am doing, and by the end of the day, all the time is up because I've either wasted it not doing what I wanted myself to be doing or doing those things, but not doing them whole heatedly and completely, because I was lost in random thought and distractions. So I'm thinking I'm going to start planning my days hour by hour, and wholly investing myself in whatever I am doing during that specific time allotment, utterly focused, without a wandering mind. At some point in my day, I will allow myself some free time, during which I can do whatever I want. I will even plan reddit time, or time I want to spend with friends or reading. I might even include an hour in there for my mind to wander and be creative.

For instance, under this new schedule, I would have allowed my mind to wander during a specific period of the day, written it down during that period, and then done whatever was next on my list (probably practicing French) until it was my 'ask online questions' period, and then I would have typed up this post. Then, maybe 15 minutes after that, it would be my reddit aimlessly period, in which I would browse. Maybe the next day would have a period 'check your posts on reddit for replies'.

What does TRP think? I think this is the best idea I've ever had.
