Loving your life is kind of an abstract concept.
I love being alive, that I do. There are many things I love doing and experiencing and I couldn't do them if I were dead.
Do I love every thing I do or experience at every hour of the day? Certainly not, e.g. I don't enjoy my back pain.
Do I think I've taken the best decisions in life? Nope.. but they were not terrible either.
I don't really have many regrets, I mean, if I didn't do or achieve something because I was an idiot, then the person that was not an idiot and could have achieved that is not me; simple logic, I don't have regrets of not achieving something I could not realistically achieve. But I guess the few regrets I have is due to me still not realizing that that particular thing was simply not meant to be for me at the moment.
I don't think I strive for anything world changing, or anything that has a purpose for humanity. I just enjoy being with myself and with the small group of acquaintances, friends and family I have contact with. Actually I also enjoy solitude, travelling alone, just looking at the stars in the middle of nowhere, play some random videogame (almost always single player games), reading books/manga/comics on my own, etc. Though I would admit I feel lonely sometimes, but I also feel overwhelmed when I feel like I don't have my space (and that happens quite fast when I am not alone).
I guess as long as I live I can still do stuff I would like to do... but also I don't believe I care so much if I died, nobody really depends on me, and I wouldn't be able to give a fuck if I am already dead. But I prefer to have a choice of doing things, so being alive is better certainly.
Still, I am not sure if any of this has anything to do with the question "do you love your life?".
I think I would mostly reply like some temper above, I simply exist. But I enjoy existing.
PS: No idea what loving life is about anyway.
