Your succulent looks quite normal for a mature plant. The leaves are plump, fat and healthy, showing some of the dusty bloom that they use to protect themselves from intense sunlight. The reddish tips are also normal for a high light plant, and the fact that a pup has appeared and some outside leaves are dying off indicates that its interior chemistry is changing over to flower and seed production mode.
No action required, sit back and enjoy the flowers when the inflorescence emerges. Learn to judge water requirements by how inflated the leaves are. Puffy leaves means no water required.
