The Bible does not say a lot about the early life of Moses, but we do know this much:
The Bible says that Moses became the son of Pharaoh's daughter (Exodus 2:10) and so when he was about 12 years old he would have lived as a prince.
The Bible also says, "And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and in deeds." (Acts 7:22) He would have been schooled as if he would someday be the ruler of Egypt and this would have given him many skills that God would use later to lead His people across the desert. This was 28 years of training that none of the other slaves could ever hope to receive. (Our God is so awesome!)
