I have a full-time job, I run an online business on the side which I'm trying to expand, and I'm starting a graduate course in a few months which I need to study for. On top of that, it's very important to me to stay physically fit and train in martial arts, which requires time in the gym as well as time in the kitchen cooking healthy meals.
I've spend a lot of time thinking about how to fit all of this in my schedule. (Part of the solution is that within the next month or two I will quit my job as I'll have enough cash to last a year or so; however this will not solve everything.)
In order to manage the tasks, I have devised a general scheme in which I separate my endeavors, and from there it's just a matter of assigning the hours of the day to different tasks/projects.
This works fine on paper, but the system is far too fragile. For example, if I don't go to bed on time one day, it throws off most of the rest of the week, as I simply can't keep up with a precise schedule when all I want to do is sleep, and I have to make a decision between staying up late again to catch up with my work, or sleeping half the day and losing more time. Or, if I choose to go out and meet a friend/girlfriend one evening, I have to skip the gym, or skip working on my business, or cut from my sleep, or skip cooking and have to eat an unhealthy sandwich at work the next day, etc.
The resultant problem is that I've reached a point where the time devoted to most of my endeavors is too fragmented to be beneficial. e.g. I go to the gym a couple times this week but then I don't make it to the gym at all next week. Now with exercise you can't just train one week and skip the next week, it makes the entire process useless, which is incredibly frustrating. So frustrating that the next time you go to the gym it's hard to be motivated to train because experience shows you might not make it next week anyway.
Same with my business; I have work that I started months ago that still hasn't been finished. The interruptions make it hard to focus on any task, as soon as I get started on something I have to get to bed to go to work in the morning, or I have to go get to the gym, etc.
I took a break from everything the last 2 weeks to think about it, and I can't really think of a good solution.
Is it the case that people are not meant to multitask? Or am I doing something seriously wrong?
