Why Can't I Hardflip?

For the longest time frontside anything has been hard. I learned Ollie 360 Kickflips and Nollie Backside Heels dow a 4 Stair Before I learned how to Frontside Shove. I can easily do them switch though and I can switch hardflip and switch frontside bigspin a 4 Stair. But I can't regular hardflip. I can barely frontside flip but switch I have it every try. I'm not sponsored but I'm making a video and the bigest i've done is ollie an 11 and kickflip a 10. I Treflipped an 8 and Backside Flipped a 10. It's just the whole idea of frontside and kickflip at the same time is too overwhelming oh and i'm 16.
