Nope.
And that's not self-depreciating. I've got a very high standard of what truly living is, and I don't think it's ever possible for anyone, let alone me, achieve it in its fullness. There have been short times where I would say, for that time, I have - when I was sitting with my father in a cafe in Paris, waiting for the train to Frankfurt, and I phoned back to North America to ask a girl I liked to coffee - and, having secured a yes for that, smoked a cigar and talked to my father for several hours on the topics of philosophy and theology. Well... in those few hours I truly lived. But until every waking moment is so, I cannot honestly say I have really lived.
Of course, I understand that it is humanly impossible to achieve the standards I hold before myself, so it is not so much that I have regrets, but a hope that I can always do better. So it is an optimistic no. So long as there is room for improvement, it must be no, so as to provide a motivation to improve. If I said 'yes', that would be resting on my laurals.
There is also the idea of being truly one's self. Truly being as you are meant to be. I'm not sure I've done that yet to the right extent, and until I have, that is another reason I cannot say yes. It is, well this is a negative example, but the idea is the same. In the play Medea (I think it's Seneca's I'm thinking of), the heroine has done many terrible things on behalf of Jason. Now that he abandons her, she resolves to things that far outmatch all the others - and she names those earlier exploits child's things to accentuate this. When she does all she intends, she has truly become 'Medea', the destined Medea in all her fullness of her character. Like I said, a negative, in that it was doing nasty things that she was destined for, but the idea is still the same. Doing what you are meant to do is truly living. From the way I see it, being a teacher is that purpose, and until I come to that point, I'll not have truly lived. When someone calls me 'professor', well, I think THAT might be something. Or, then again, maybe not. Maybe at that point there will still be more.
I will say, however, that I think I've come closer to living than the majority. My studies, the simple desire to want to know one's self and know the world, contribute to truely living (to borrow the idea off Seneca, that they who engage in study and thought are the ones who are truly living.) Experiences, doing things... I wouldn't count these as true life unless they are deeply considered. You see, an animal can 'live', and an animal can have experience, and do things, but that is not considered true life in the human sense. It takes more, it takes doing things with thought, that makes human life.
