Raise the back of your tongue to touch the soft palate. Add vocal cord vibration, then release.

Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.

Start with your mouth slightly open, then close your jaw slightly as your lips round. Shift your tongue back slightly, then stretch the back up.
Press your lips together, add vocal cord vibration, then release.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "globe", the "b" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
