Explore Google AdWords Tools
If you have read and understood all previous pages regarding to Google AdWords PPC, you have gained the essential knowledge to start your own Adwords campaign.
There are many areas that I didn't cover such as Google's Advanced Search and Editing Tool, Google's Ad Diagnostics Tool, Google Analytics, Reports and many more. I feel that those areas should be acquired by experience.
Google's Free Tools
Spend sometime to get acclimated with Google AdWords advertisement, and the available free tools that Google offers. Every body has different learning curves, so take your time to learn at your own pace. Once you think you know enough about Google Adwords advertising tools, then you can move on and learn other tools or software available to make your Adwords Ads much more competitive.

Learn from your competitors who have many more years of experience than you do. Once you've locate them, then you can study and mimic what they do to become very successful. You'd need tools to help you learn quicker, and to have the cutting edge advantages over your competitions.
