It's a toss-up between the Op-Ed and the Comics.
Depends on the type of immortality. If it's like the Elves in the Tolkien Universe where I live forever unless killed, I would probably become nihilistic and possibly suicidal after I believed I had obtained all possible knowledge. That may take a thousand years or a billion, but I would get bored eventually. If it was true immortality, I would stop aging the day before all these age lines in my face appeared.

I know too much about temporal mechanics to answer this question without being anal-retentive. If we live in an Omniverse, reverse time-travel is impossible. I would be stuck in the moment my time machine activated and since time itself will eventually end, being stuck in that loop forever is a paradox. Even if it is possible ... think of it like this: If Marty McFly actually went back to 1955 and met his own mother in a linear timeline, she would have retained the memory of meeting him even "before" he made the trip. Furthermore, even if his presence hadn't been observed by a whole town full of people, the people in 1955 would have no immunities to the 1985 bacteria he carried back with him, and he would likely have caused a pandemic that killed millions. Regardless of what I did, however, I could only live my life up until the very moment I was required to repeat the time travel, which is just a paradox stretched out over a longer period. If we live in a Multiverse, I might be able to travel to a universe which has the same physics as ours and exists in what we perceive as the past, but whatever I did there would have no effect on my original reality. In that case I would visit other-me the day before they had a particular appointment with a particular head-shrinker at 15 years of age, and advise them to be honest. Simple. Inception, perhaps. But I wasn't always the good person you all know and love today.
Tempting, after the previous question, to reply, "A time machine." But if I was T'Challa or Tony Stark or Bruce Wayne or Adrian Veidt (why aren't there any women in comics with unlimited resources?), I would fund fusion research aimed at virtually-limitless energy production, which would hopefully result in world peace but would more likely result in us seeking other excuses to be barbaric toward one another. Once achieved, I would create a containment device that could withstand the gravitational pull of super-massive objects like "black holes" and use it for space exploration.
I don't have a bucket list, and the only thing I really want to achieve before I die is to own an industrial hemp farm. I don't have the resources to do so on my own (apart from all the other things in everyday life), but I do have a plan to get there. Now if I could just get my brother to focus, or find some investors ...
A Theory of Everything. Because it's probably unattainable without an objective measurement of our Universe's geometry, which itself is probably impossible without a power source capable of providing enough thrust to overcome the gravitational pull of all the mass in the Universe. I wrote a little bit about this here.
The Philosophy of Physics.
Tool.
I can't answer this "recently", because I haven't had much time for books - we have hundreds here but I've read maybe a third of them - but my favorite book is probably Buffalo Soldiers by Robert O'Connor. The best movie I've seen recently is probably Isle of Dogs and my all-time favorite movie is probably The Departed. Because they are reflections of reality.
