I will add one thing, it takes between 1 to 2 months to have the routine be really part of your daily life, but it takes 1 week to lose it! What is really important is that you never forget the hard work it was to build the routine to never let it go. It is hard for everybody to build again a routine after a break like when you broke your foot (like me right now) and need to go back to running every second day (I know it will be painful both physically and psychologically for me). Point 5. is really important. One habit at a time, it takes a lot of willpower to build one action/activity into a routine, do not overload. Also, there are some habits which are easier to start building at given point in your life or of the year (running in winter may not be fun for you). So use the right time of the year, the right break in your life to start something and fight to not lose the ones you achieved.
