My two cents: Keep a journal -- do a spread every day (perhaps a 3 card daily spread) and write down cards, meanings, and your interpretation. Doesn't have to be fancy or lengthy, just some quick notes and impressions. Don't worry about reversals for now.
After a month or so, you'll have written about -- and THOUGHT about -- most of the cards. You'll begin to see cues in the card pictures (and that's why I like RWS and clones) and the card meanings. Soon enough, you'll find yourself thinking deeper about what the "vignette" on the card is suggesting ("So he's smiling -- but WHY?" "This persona has everything -- but is he satisfied?", "They're trapped -- but the ropes are really loosely tied, so they could get away if they tried.", etc)
I found myself spending a little "daydreaming" time where I would have a conversation with the characters in the card -- asking them how they felt and why. Soon enough, the characters and settings on the card will become very familiar.
The nice thing about learning the cards this way is that it gives you the tools you need to go a little further ("If the two cards feel certain ways individually, then how will they react when I put them together? What will change?").
