So, if your H doenst want to do the whole routine as decsribed, you still have (maybe even the same) chances to make it.
Sorry, Kalni, I have to disagree with this. Yes, you can still make it, but it's simply much more DIFFICULT than if you do as many things the right way as possible.
None of this stuff is guaranteed; it is, however, all about MAXIMIZING YOUR CHANCES AT SUCCESS, by applying as much of the effective strategies, tactics and concepts to your situation as possible.
