My "Productivity System"

During the last many months I've been reading about productivity like crazy. Some of the great people around are coming up with highly effective systems for efficient time management and happiness. I'm lagging in the race and hardly know beyond the ABCs of Getting Things Done, Zen To Done, or Stephen Covey's Seven Habits of Highly Successful people. Recently I read an article on Stepcase Lifehack (one of my favourite blogs) on why you should learn a productivity system. The basic idea is that people who make these great productivity systems have loads of experience and knowledge to be sure their ideas are practically successful. This is what they do best, and we should leave this job to them.
The information overload on productivity was making me guilty somewhat, because I seem to be the only one not managing all my tasks according to a world-famous system. I'm still not perfectly convinced that this is a job best left to the experts. If something works for you, use it. If you can't decide what's best for you, the experts are always there to help. Makes sense to me! So yesterday I got thinking, and realized that, no matter how simple, I do have a productivity system after all. My very own! And here it is:

1. If you want it done, schedule it.
Every task that needs serious time and attention from me has to be planned. I don't have a fancy notebook or software that keeps track of these things. My to-do lists are usually in the form of a note to self on my cell phone, or as a new sticky, or penned down on a small scrap of paper that stays in my wallet. The idea is simply this: if something needs my time, it has to be scheduled. Maybe for "some time within this week" if I can't focus on the timing too well, but usually my to-do's are on a daily basis.

2. Acknowledge the importance of voids. (An idea originally Umberto Eco's.)
Even when I plan each hour or so of my day, there are always voids I keep in between. Rather than keeping time aside for relaxation, I use the voids. An example of this would be:
4-5.30 pm: Math
6-8 pm: Physics
9 pm: Revision
So after I'm done with math I know I have some time for a tea break. This also takes care of things that unexpectedly pop up, and there's some room for stretching in case math takes longer. Similarly, after physics I know I have enough time for dinner and walk and if I have time to spare it can be used for something unplanned.

3. Plan more than you know you will do.
My usual daily plan has about 110% of what I really want to achieve within the day. Goes with the idea of "Shoot for the moon, and you'll at least land among the stars." I make sure the more important tasks get higher priority, and at least those get done for sure. And sometimes I actually end up doing the extra tasks as well.
So this is how I (try to) stay organized. My system is far from perfect and I keep borrowing ideas from the experts to make it better. So far I'm managing just fine this way. If ever I think I'm overwhelmed, I know there's David Allen or Leo Babuata (among others) to help me out!
