Years ago in the early days, I used Picasa. I tried Photoshop Elements when I started looking for more control. I never warmed up to it, but instantly felt comfortable with Lightroom when I finally tried it. I really like the organizer functions of Lightroom too. Now that I recently signed up for Adobe cc, I am feeling much better about Photoshop than I did with Elements. Not that full Photoshop is any easier, but I think the pressure is off because I get most of my needed results in Lightroom and I can take my time now and just enjoy the Photoshop learning.
To the OP: tag your photos in Lightroom with keywords right from the start. You can bulk tag too. I tag in waves, I might tag the whole batch with a location or major feature like 'lake', then I go back later and additionally tag with more precise words, like 'bird', 'duck' etc. It goes quickly and saves you a big project down the road if later decide you should have tagged the images.
