hong said:"Under conditions of peace, the warlike man attacks himself" -- Nietzsche
Now some have interpreted this in the literal manner, to suggest that a warlike man will self-destruct when there are no wars to fight. This is, of course, silly. Much of Nietzsche's work, like that of most great philosophers, was written with many possible interpretations in mind, and to latch on to the literal one betrays a lack of consideration.
No, the way to interpret this is in the metaphorical or figurative manner, to ask what it is the words might _stand for_, not what they literally mean. And in this case, just a few minutes' reflection will reveal the true meaning of the phrase given above. War, of course, is a violent state of being. Violence is abuse, and a warlike man is one who engages in abuse. And when there is noone else to abuse, a warlike man must engage in self-abuse. If you know what I mean, and I think you do.
I hope the way forward is now clear. There can only be one course of action for your paladin to take for the next five years. Good luck, and godspeed.
Hong "and be sure to stock up on lubrication" Ooi
Really, should we attempt to understand a PHILISOPHICAL statement in a METAPHORICAL sense? ... Man I have been doing it wrong all these years.

Seriously though, I must comment on the reasoning Hong gave, and on the given philosopher.
While Nietzsche did much for philosophy, I really wouldn’t call him great. Of course one would disagree with me if they excepted most of his ideas, and that is not because we merely disagree in our favor of him. Rather it is with the idea of the word "great", and what a "great" man would strive for/to be. (maybe "great" [used loosely] as a philosopher).
Nietzsche threw himself against everything that is good, claiming moral conscious to be a weakness. Among other things, I am thinking a Paladin would have quite a hard time seeing eye to eye with him.
A Paladin is only "warlike" when he is faced with evil. Secondly, battles can be fought in ways more effective then using a sword. Not all are physical.
I must disagree that "warlike" must mean "violent." Some wars are quite just and necessary, if only to be a last resort (such as when a Paladin is faced with demons) and so men who fight these wars need not be violent.
Secondly, violence also does not necessarily mean abuse. Again, if we look at War, even though violence occurs, I would hardly call smiting an evil foe a matter of "abuse."
I think Hong were being to liberal with the meanings of some of these words.
Now, I know that Nietzsche's statement is only, at best, a generality, and of course we can all see truth in that given occurrence, so I will stop there.
Anyway, Bozidar, there have been many wonderful suggestions for what a Paladin could do when not on an adventure or quest to go slay some evil necessarily.
It can be safely assumed that going on adventure during those five years is going to be viewed as unfavorable by your DM, and might mess with his plot, I would avoid any of that.
Since 9th level is nearing legendary status, and Ryn is sure to have great Charisma, so becoming some sort of Lord or leader of a community would be fitting. You could thread that very thing with building his own keep, finding a romantic interest, starting a family, founding a place to teach and/or shelter the young and needy. If he indeed relishes combat, defense of the community, and training could be fit in this way as well (of course assuming that the community is in need of defense may need checked by your DM). Or perhaps if he manages to start a family, his mindset (especially when considering battle) is altered?
