If you're not, then I suggest you read Danny's posts o australia business email lists n learning SEO. While you're reading through this list you might want to motivate yourself by reminding yourself what you can earn at different job levels within the SEO indsutry. 1) Get Qualified Although I'm not a huge fan of qualifications generally and certainly in the SEO industry they're few and far between, but nevertheless - getting either GAIQ or Adwords qualified will look good on a CV and give you some valuable skills.
Not to mention they're pretty easy and cheap so totally learnable in your spare time! 2) Learn Some Secondary Skills SEO, or more broadly internet marketing, covers such a wide range of topics, skills and industries that it never hurts to have more strings to your bow than just linkbuilding. Try teaching yourself some PHP or CSS. I recently learned a few CSS bits and pieces and they come in handy for styling blog posts (Rob gives a good intro to learning CSS for styling blog posts here).
