1. Search and carefully read the documentation.
2. Write code (this can, unfortunately, require significant effort.)
3. Test your program.
4. If it fails, fix it. If you can't figure out how to fix it, re-read the documentation, search the Web, and - if none of the above helps - post to Perlmonks, citing the exact error messages and a minimal code snippet that demonstrates the problem.

People who follow the above, or some similar procedure, usually get lots of helpful answers - not just here, but in almost any help forum. People who don't usually get annoyed or less than helpful responses - although sometimes, someone will take pity on these clueless individuals and give them an answer - say, as a Christmas present.

You should consider carefully into which category you fall, and fix it quickly if it's the wrong one.
