I'm 26 years old, and I haven't achieved anything yet. Now I want to study pediatrics of traditional Chinese medicine with my relatives again. I wonder if it's too late. I didn't study before because I wanted to try something else. It's not too late. A 26-year-old has good conditions in all aspects and can learn things faster. However, learning things requires patience, especially in medicine. You may encounter unexpected difficulties at first. As long as you persist and keep learning, I believe it will get better and better. Keep at it. You are never too old to learn. Come on.
