Book Reports / Explain three of the most valuable lessons learned by King Lear [2]

Hi guys! I am taking ENG 4U and I need help with this question.
In a unified essay of 1000 to 1500 words, explain 3 of the most valuable lessons learned by King Lear from the beginning of the play to the end of Act 4 (IV). Explain the significance of each lesson learned and use specific references to the play to support your ideas.

Thanks for all of your help.
