My advice echoes many of the posts here…
Journal..
Pull cards and write down what you see, how they make you feel, what you think they mean etc.. I find it helps to do this at the end of the day and ask for a card representing something in your day.. Look at the card and try to relate it to something you've done, that's happened to you or that you've thought that day..
Another thing I've found really useful is to compare the cards of the same number in the different suits.. Tarot is divided into suits each ruled by an element but the numbers are the same.. Compare all of the Aces, all of the Twos etc and look for similarities, differences…
Read about elements, numbers, colours, symbolism.. A symbol dictionary is a good buy.. The cards all contain readable symbols and learning to actually read them is like learning a new language; it takes time and a lot of time at that..
It's a journey, don't rush it and don't worry if you feel as if you're not getting anywhere; believe me, you are.
It took me years until I felt 'fluent' in the language of the cards and as Nisaba said, even when you've been reading for decades, you'll still be learning…
You can pick up enough to get by quickly but to really, really know how to read takes a long time..
Enjoy yourself, play with your cards, make up stories with them, do imaginary readings for imaginary querants, read books about them and try not to look up the card meanings whilst you're actually doing a reading - it really is all there in the cards
.
Stick to small spreads - 1 to 3 cards… Adding more cards will cause you to skim over them and you'll miss the deeper meanings…
As you go on you'll gather layers of knowledge and it will all start to become clearer - honestly it will
