My son was a real champ - super easy peasy to train. We did it when he turned two, and within a few days, he was mostly accident-free. We made a really big fuss about it, praised him a lot, and rewarded him with sticker rewards (his favorite!). That really motivated him. He's always been a straightforward kid, so once he realized the potty was for peeing and pooping, that was it - no accidents after the first week.
My only tip is to follow your child's cues and don't force it until they're ready - it makes such a difference! We had a more difficult time with our daughter; she wasn't interested and liked her nappies, so it took much longer. But that's another story! Also, don't be afraid to use incentives - stickers worked wonders for us! There's no shame in it - it's a great motivator!
