My Linkoln concept

I've been thinking about it for a while and I think I am ready to begin now.
The concept is that you have some good habits that you want to gain. Then you give yourself a week to live with the habit as if you have it already and you focus on it only. The next week goes with another habit etc. When the list of habits ends you begin again, mastering them as much as possible. (though it does not appeal to the Toyota's concept when if you are going to get rid of some bad habit you do that once and forever)
So, I have a few ideas in my mind.
1. get up early
2. prepare for each class
3. speak up at every class
4. read every day
Something like that. I will see if I am really going to try this. Because telling yourself 'it is just for a week' can have different results after a week's time.
