Where Do You Go from Here?
The next big step you need to take is to begin experimenting with your scripts. There are many resources on the Web that will help you rapidly expand your knowledge. Then you must get OS 10.4 Tiger so you can integrate your scripts within Apple's new Automator solution. Automator is the tool that allows users to take blocks of code and rapidly generate a solution without any coding. Of course, there is coding created to build the blocks of code, but this is where you come in. You can show off your skills and provide solutions to the rapidly growing Mac community.
The final step is a big one. Break out of AppleScript and being working with one of the power languages such as Xcode, OS X's code environment, and Java. Apple is making freely available development tools for you to build solutions in Xcode. The tools and help you need are available—all you have to do is come up with the Killer App and retire to the Caymans.
