What skateboard trick should I learn next?

I can ollie, FS and BS shove/pop-shove it, and FS and BS half-cab. I know that the obvious answer is probably kickflip, but I am nowhere near landing it... Are there any more basic tricks I should learn? If I should jump to the kickflip right away, how long will it take me to land? (I can only flip the board halfway...sometimes)
