Pace yourself. It took me 30 years to finally finish, but I loved most of it. Though some of volumes 5 and 6 were a bit of a slog. Too much obsessing over Albertine.

You be you. Nobody cares what you consider 'read'.

Foyles, Hatchards are two I like.

In 366 days you will no longer be a teenager, so look forward to your 20s with lots of enthusiasm.

Check out some of the rare films released on the Criterion sub-brand Eclipse. There are over 40 (DVD only) boxsets of some more obscure directors and unknown films from all over the world. Some of my favorite sets are the Czech New Wave, Late Ozu, Early Bergman, Larisa Shepitko, Hiroshi Shimizu, Chantal Akerman, and many others. There is also the World Cinema Project of boxsets (3 currently) with multiple films in each set, restored by Martin Scorsese and also released by Criterion. These are unknown films from non-Western countries (mostly) that should be watched by more people who love film.

Here's a thorough list of all the Criterion boxsets. You could learn much from viewing many of these -

Some of my favorite classes at university were part of a 6 class series called History of Science, Philosophy, and Literature. I took 4 or 5 of them and they were very good as they crossed multiple disciplines.
