Easy thing #1: Try logging in daily. This will at least give you a Loyal Bazaar membership store pass.
Easy thing #2: Play daily chance for prizes. Sometimes you can get rare things.
Easy thing #3: Explore. Learn your way around Gaia can help you in yhe long run and also you can snag up tiny bits of gold too.
Easy thing #4: Play the marketplace. Buy and sell but stay within reasonable means. You want your earnings to be big and your spendings to be small.
Easy thing #5: Play Gaia games. Try out Tiles and fishing. These are the best ones in my opinion especially if you looking for quick gold.
Easy thing #6: Save up. If you have itchy burning fingers create mule account to place half of you gold and items into. Also try buying items in bulks.
