Some things to keep in mind:
1. There is no such thing as a magic drill... and there are rarely TRUE silver bullets.

2. Hard work is pointless without intelligence.
3. Patience...
4. The sand pit and high bar are your friends... BEST friends (especially if you're using a stiff pole in the sand pit!)...
5. There is a search button on this site.
6. It takes ~10,000 hours of practice to 'master' a complex task... This includes pole vaulting. Do your best to avoid getting too frustrated.
7. Set reasonable goals.
8. STAY HEALTHY/UNINJURED! Be concerned greatly about preventative safety.

9. Know the rules of the sport.
Good luck!
