Use the first person pronoun. This is YOUR insight. You might also need to initially clarify certain terms. Once clarified, use the same term throughout. Use neither different terms for the same purpose (do not consult a thesaurus), as this could alter the meaning of your claims, nor the same term for different purposes. For instance, if by 'cleave' you mean 'to adhere', do not later use 'cleave' for 'to separate'. Use simple, direct and clear language throughout your paper.
