Most of the time:

If you find a strategy confusing, it’s overly complicated.
If you don’t understand a document, it is poorly written.
If you can’t grasp a concept, it is badly explained.
If you can’t use a product easily, it is shoddily designed.
If you don’t know what to expect from a service, it is inadequately communicated.
If you can’t navigate a range of offerings, it’s not been put together properly.

Trust your abilities. If you don’t understand something it’s probably not you, and you’re probably not alone.

Don’t worry about looking stupid or whether you're not smart enough to "get it". Worry about what happens if nobody speaks up about sub-standard work, unintelligible plans, or decisions that will ultimately make customer's lives more difficult or cause products to fail outright.
