[I'm sleepy so bear with me.] Meditation is extremely easy - for a while. I'm interested in it, I try to do it regularly, but it's not easy to return to it every day, or during a busy day. We see a news article about it, we talk about it, some of us will try it for a while, but in a month from now, all of us will be at the same point as right now - not doing it anymore. It's hard to stress how important is to practice regularly, as then it starts to be
really effective.
In my life, I'm returning to meditation in waves, in short periods of practice, but for some (possibly material, possibly immaterial) reason, I want more.
My aim is to find a way how to meditate sustainably, with the least effort, and how to remind oneself every day that he should meditate. Mind you, I don't know if this is even viable, as sometimes your mind revolts, and when it does, it will (on the background) use your best intelligence and creativity to avoid the practice. I think that not even smartphone apps can help you in this regard. Speaking of which, so far I've seen two worth mentioning (I haven't tried them yet), this one for iPhone

https://market.android.com/details?id=com.nwalex.meditation. But as I said, I'm not sure these can help in a long run. The problem is that as you keep practicing (internal-awareness) meditation regularly, it will change your external reality (a.k.a. your life) very profoundly, only making it harder to keep practicing every day. There's a lot more to write about this, I could go on and on for many more pages - distractions, formal vs informal, beating your daily energy deficiency, cheating the thought-switching mechanism that makes you day-dream during meditation, etc.. but I want to put this in a readable and practically usable form first, if that is possible at all. (Edit: oh, and it must be a
very short form - if you write a book about meditation, then - I believe - you have already failed to deliver what matters, as in that case the reader will simply get satisfied/their energy depleted with the reading itself, and their focus moves to something else.)
