Why 30 days?

I stole the idea - plus the Business Course is only 30 days or so i.e. until Study Week.

In those 30 days a lot can be achieved...

Anyway, as I say, I stole the idea:

"A powerful personal growth tool is the 30-day trial. This is a concept I borrowed from the shareware industry, where you can download a trial version of a piece of software and try it out risk-free for 30 days before you’re required to buy the full version. It’s also a great way to develop new habits, and best of all, it’s brain-dead simple.

Let’s say you want to start a new habit like an exercise program or quit a bad habit like sucking on cancer sticks. We all know that getting started and sticking with the new habit for a few weeks is the hard part. Once you’ve overcome inertia, it’s much easier to keep going.

Yet we often psyche ourselves out of getting started by mentally thinking about the change as something permanent — before we’ve even begun. It seems too overwhelming to think about making a big change and sticking with it every day for the rest of your life when you’re still habituated to doing the opposite. The more you think about the change as something permanent, the more you stay put.

But what if you thought about making the change only temporarily — say for 30 days — and then you’re free to go back to your old habits? That doesn’t seem so hard anymore. Exercise daily for just 30 days, then quit. Maintain a neatly organized desk for 30 days, then slack off. Read for an hour a day for 30 days, then go back to watching TV.

Could you do it? It still requires a bit of discipline and commitment, but not nearly so much as making a permanent change. Any perceived deprivation is only temporary. You can count down the days to freedom. And for at least 30 days, you’ll gain some benefit. It’s not so bad. You can handle it. It’s only one month out of your life.

Now if you actually complete a 30-day trial, what’s going to happen? First, you’ll go far enough to establish it as a habit, and it will be easier to maintain than it was to begin it. Secondly, you’ll break the addiction of your old habit during this time. Thirdly, you’ll have 30 days of success behind you, which will give you greater confidence that you can continue. And fourthly, you’ll gain 30 days worth of results, which will give you practical feedback on what you can expect if you continue, putting you in a better place to make informed long-term decisions.

Therefore, once you hit the end of the 30-day trial, your ability to make the habit permanent is vastly increased. But even if you aren’t ready to make it permanent, you can opt to extend your trial period to 60 or 90 days. The longer you go with the trial period, the easier it will be to lock in the new habit for life.

Another benefit of this approach is that you can use it to test new habits where you really aren’t sure if you’d even want to continue for life. Maybe you’d like to try a new diet, but you don’t know if you’d find it too restrictive. In that case, do a 30-day trial and then re-evaluate. There’s no shame in stopping if you know the new habit doesn’t suit you. It’s like trying a piece of shareware for 30 days and then uninstalling it if it doesn’t suit your needs. No harm, no foul."
