I didn't tried it, but I believe I wrote my own gamification system. It is a simple time tracking system with a history viewer, from which I clock in my activity for the day. I have my own goals that I tried to achieve everyday. It was very effective in keeping me working 30 hours each week for 7 weeks so far.

Happiness and Productivity. Living Alone. Living with Friends. Living with Family.

My parents think that I don't work at all, and I prefer to keep it that way, at least, until I achieve some measure of financial success.

A Workflow with Spaced Repetition

My workflow is that I spent 30 minutes a day going through the cards. I do them all until I complete them. Usually, that mean I finish them all within 30 minutes. If there's spare time, I learn some new cards until 30 minutes is up. Otherwise, I never learn anything new that day. Over half of the content entered is never reviewed before, so I have quite the reserve.

Usually that mean hundred of cards are studied everyday. Then I spend 5 minutes editing my cards, either for errors, or for fact checking.

Another Anki deck for Less Wrong content

As much as I like reading the sequences, I am skeptical about their utility in increasing rationality, or rather, the rationality increases in the lesswrong community is not measured or quantified scientifically.

How many of you doing Khan Academy?

Well, I meant doing the exercises. I don't spent much of my time on the videos because either I already know it or I figured out either with the hints or without. Then, it's smooth sailing the rest of the way.

How many of you doing Khan Academy?

Well, since I am almost complete the whole thing, I have 1.3 million energy points, and 4 suns and 2 earth badges in additions to all the moons and the meteorites.

How many of you doing Khan Academy?

That's a question that cannot be answered without looking at math major's area of focus or their specific career of choice, of which I am ignorant about.

That being said, I don't think a math major or a person who is in a strong math related field necessary focus on everything that requires high school mathematics. They may not touch statistics, or linear algebra as often as other area because they don't need it in their day to day job. They may need khanacademy to reviews those area that they didn't touch.

In a highly technical field like programming, most programmers may not need to deal anything more complicated than algebra, so they're going to forget the more advanced aspects.

How many of you doing Khan Academy?

Did you do any of the exercise? How much if you do so.

How many of you doing Khan Academy?

I don't think khanacademy is just for high school kids, or elementary or middle school. Everyone will forget, and almost everyone with a high school education or better will have gaps in their knowledge. Everyone seems to think that college is the end of their education, but that's false. As with everything you learn or master, you need to practice them, and khanacademy offers periodic reviews according to the principle of spaced repetition.

So, it's great for adults too, even if they're only in review mode for the vast majority of their life. When they start to learn something more advanced, they don't have to go back to elementary math or deal with the problem of knowledge gaps.

Only the youngest can derive much benefit from it? Absolutely not true.
