The Rule of Five is a great principle - but the rules about what 'counts' have to be individual. If you are trying to get going with some network marketing and finding it a challenge, sending your material to five different people every day might be exactly what you can handle to get you moving. If you are trying to come out of a depression, getting five basic household chores done each day definitely should 'count.'
I believe in 'baby steps' - and preferably one at a time with a celebration of each success! Don't make the details of following the rule of five too complex. If I have to figure out if my choice of actions will 'count' according to 'the rules,' I probably won't spend the time to come up with five 'acceptable' actions. I advocate that everybody should choose their own five actions for reaching towards their goal with an eye to their being simple enough that it will be not only possible, but easy (effortless, if you will) to succeed - and then acknowlege their successes. I also advocate that everybody repeat their five actions as long as necessary to make them a habit (if they need to be a routine part of your life or business) before adding very much more.
That said, I will confess that I have not applied the rule of five myself, although I clearly see it's value. I'm probably upper-limiting on something here!
May you create a new and higher set point for happiness today!
