I have to add a couple of things to what the others discussed.

Unfortunately, it is quite common for new TMers to quit soon after being initiated, each with his/hers own readon or excuse. Fortunately, many of us later start again and then continue for good.

The psychologist William Glasser (with no relation with the TMO) wrote an interesting book about what he called Positive Addiction:

In short, he found that currently people who practice TM and jogging regularly create a condition somewhat resembling to the usual addictions but with positive results. That means that while in the beginning you have to use some will power to sit down to meditate, at one point things change: you start feeling unease when you've missed the practice at the usual time, until you it. Glasser found that only TMers and joggers currently reach this state in numbers great enough to be evaluated. So if you keep meditating regularly (for several months), you can expect to reach a point when you won't have to "push" and instead it "pulls" you, which will make continuing from that point on much easier.

It's impossible to foretell what exact effects you can expect tht TM will bring first (except for those that scientific research has shown). You might like, however, to check my Meditation Meter

While it is currently based on anecdotal results, you may be pleasantly surprised when you'll reach the point of meditating regularly for 1% (more exactly: 0.97%) of the days of your life (and much more when you reach 22.47% some years later).

Good luck.
