I don't want to pour cold water on your optimism but - unless you are a prodigy - it will take longer than a couple of weeks.
Lr is a complex and demanding program, and it needs time to learn well. And only when you are good at at can you enjoy "playing" with your photos.
So don't put your hopes too high, or you'll be disappointed soon. And that would be a shame because Lightroom is worth the effort.
I work with it on a daily basis, and I can't imagine doing my work without it. But it's a steep learning curve.
Keep up the good work, and if you run into questions, you know the place where to ask them.
