If you enjoy getting the achievements and reach the point of frustration trying to get them, then yeah consult a guide. There’s nothing wrong with that.
When I’m enjoying a game and reach a dead-end like an impassible door that by rights with my huge arsenal I should be able to just break down, I have no problems “consulting the townspeople” to see what particular trick the game has in mind. Sometimes the trick makes sense, sometimes it’s something I would have never thought of and makes no sense. In that case I feel good that I didn’t let the game waste more of my time on it.
