Sam, if you are currently certified, then why do you need to re-certify? Like LatitudeAdjustment stated it depends where you where certified and plan to dive. But the main thing is your question "Can anyone help me become a better diver?" this is entirely up to you. Dive more, but dive SMART and learn with each dive. There is a lot of information providers (PADI, DiverAlert, Dive Medic, etc) for tips and knowledge facts. In closely, it all comes down to knowledge and experience.
