First, that avocado is under-ripe. They are hard until they are ready to eat and then they get buttery soft, like bananas.

Second, only the green flesh tastes good, the outer skin is leathery and gross and the pit is hard and not edible, so like a mango, you gotta skim and pit it.

And third, avocado really isn’t something you eat by itself. It’s kinda like vegetable mayonnaise, fatty but without a ton of its own flavor so it’s almost always part of a dish with some lemon or lime juice or other acid or something salty like soy sauce.
