Should I try to do other tricks other than the kickflip or heelflip?

I can ollie 16 inches high while rolling, shuvit, popshuvit, fakie ollie, half cab, fs 180 ollie, switch ollie like 4 inches while rolling, and manual and nose manual. Now, I've been trying to kickflip for like 3 weeks and I can only land half a flip with my back foot. If you can help me with this problem then help me please. My other problem is that should I try other tricks other than the kickflip or should I just stick to the kickflip until I land it? I'm asking this because I think I am progressing too slow just sticking to the kickflip, so please help me.
