A lot of great suggestions in here already. Just to throw in some more:
1. Start browsing the mountaineering and trad climbing forums here regularly. While there's plenty of stupid antics and trolling, there are also awesome discussions on gear, technique, climbs, ethics etc where you can pick up a lot of information relatively easily. If you have five minutes of twiddling your thumbs at work, it's worth it to check the MP forums just to see if any new discussions have come up.
2. Likewise, if you're on FB, look for groups related to the skills or areas where you want to climb. Pacific Northwest Mountaineers, Utah Climbing, and Utah Ice climbing, for example, are three groups where I regularly pick up really excellent tips and beta regarding conditions on different mountains and climbs.
3. Start reading Accidents in North American Mountaineering. Every time I plan on visiting a new climb, mountain, area, etc., I use their free, public search function and read as many reports as I can about the climb I'm planning or just undertook to understand what went wrong for others, and how I can avoid the same. Be careful you don't psyche yourself out, but it's an excellent learning tool.
4. In terms of books, read Freedom of the Hills cover to cover. I'm not kidding. Even if you don't plan on utilizing some of the techniques covered in that book, understanding many of the principles covered throughout all of the sections can really help translate to other skills. Quick side note: A big, big, big hurtle to get past will be glacier travel--many of the best objectives in alpinism require some knowledge of getting through glaciers safely, so reading up on them and starting to play around with pulleys etc. at your local crag will pay dividends in the future--even if you have no immediate plans to climb glaciated peaks this next year.
5. Keep up the stoke. Watch videos or read books about climbs you want to do. Put up posters of peaks you dream of climbing. I know it sounds childish, but it works.
6. Train your body. Alpinism is extremely demanding. If you run, get in the habit of putting in a lot of miles each week. Hangboard or undertake ARC training to build up your endurance. Enter a 50k race. Pick up cross country skiing. This is explained in Training for the New Alpinism, but essentially, training for endurance can also increase your margin of safety--the less exhausted you are, the clearer you can think, plan and act when things really get serious in the mountains.
7. Don't be afraid to look silly or ask questions. The only people I've ever seen at a crag or on a mountain cop an attitude towards beginners are other beginners trying to hide the fact that they're scared or insecure.
8. Be philosophical about it. Weather, partners, life events, etc can totally disrupt big plans you might have had for your first crack at Liberty Ridge or Exum Ridge or the Casual Route on the Diamond or whatever. But just roll with it. I tell myself the mountains had different plans that day--I'm only up there by their permission anyways.
9. Start doing. Get on some easy trad multipitch once you feel you've got anchors nailed down. No shame in messing around all day on a 3-pitch 5.4 with your buddy just to dial your systems. That's how everyone learns.
