If he is not ready, you can't. You have to wait until they show signs of readiness, such as disliking to be wet, waking up from a nap dry, taking an interest in the potty, telling you they are wet/poopy, being able to follow simple instructions. If you try before he is ready, it will only be a nightmare for you. If he IS ready, take him to the store and buy him LOTS of underwear. Let him pick out some cute ones, like Cars, or Ironman. Stay close to home for at least a few days and have him wear his underwear around the house. Be prepared for lots of accidents. Take him to the bathroom once an hour and have him sit. If he has an accident throughout the day, don't get mad. State the facts "you peed in your underwear, the pee goes in the potty, not your undies". Then just change him. If he poops, dump out the mess into the toilet and show him where it goes. It takes some practice and time.
