At what age should I start training my puppy?

I’ve just brought home a new puppy, and I’m so excited to start training him, but I’m unsure about the best age to begin. I know early training is important, but I want to make sure I’m starting at the right time without overwhelming him. When did you start training your puppy, and what age do you recommend for starting basic commands, potty training, and socialization? Any tips on how to make the training process enjoyable for my puppy (and for me!) would be super helpful. Looking forward to hearing your experiences and advice. Thanks!
