How Do I Become The Best Skateboarder?

Okay im a 18yr old and i first started skating at 10 and every since a kid this has been my dream to move to l.a get sponsored ride for baker skateboards and eventually turn pro but i have a couple of problems like i skate everyday but i don't feel as if im putting enough good practice into my skating it's like everyday im out skating but basically just cruising around on my skateboard i can ollie stationary but they aren't that high and also i can ollie while moving 3 out of 4 times and i just need someone who's good at skateboarding to give me answers on how to practice harder and better and also when im getting ready to ollie stairs the fear of falling and getting hurt pops up in my head so i don't even commit to doing the trick i just need someones help on getting better so if anyone has any tips please tell me..........Thanks
