Do you simply lack the time to find and read new educational material (whether books, blog posts, or articles)?
Occasional Genealogists (OGs) need education as much, if not more, than often genealogists. Your genealogy knowledge grows a lot from experience. If you don't get to research a lot, you can really be hampered by a lack of education. To make the most of your limited research time, you should try and get as much education as possible.
At some point, you've going to need to go beyond basic genealogy education and learn some more advanced techniques. But you're an Occasional Genealogist, how will you find the time?
A great resource for bite-sized, but more advanced education, are the webinars from the Board for Certification of Genealogists (BCG). These webinars are for any genealogists, whether they are certified, want to be certified, are just trying to improve their skills, are professionals, want to be professionals, or are just avid hobbyists. That's right, these are webinars for hobbyists, too.
If you feel like you keep learning the same thing over and over again from magazines, online lectures, and even blog posts, give the BCG webinars a try.
The webinars are free when they're live. A few remain free as recordings. Previously the webinars were only accessible through the BCG website but now you can register (for free) for the live webinars and purchase recordings from Family Tree Webinars.
Family Tree Webinars offers many other webinars. The BCG Webinars are most likely the most advanced. If you find them too advanced, try and find another webinar on a similar topic to help you fill in the gap between your current education and the BCG webinar.
One of the great things about genealogy is it doesn't require formal schooling. If you don't want to find yourself permanently stuck, you need to self-educate, though.
You probably need some "formal" education in the sense you should learn from a teacher/instructor, not just by reading. Reading is the primary way genealogists have always improved their knowledge. With the Internet, now we can conveniently learn from an instructor via live and recorded webinars, classes, and even on-going education.
If you're ready to move to another level but need some quicker options or a one-stop-shop for more advanced material, the BCG webinars are a great place to start.
