Writing Feedback / pleasure and satisfaction: the pursuit of our desires or the attainment of them? [4]

I don't have much to comment, except for your first sentence. It struck me with an unmistakable error: During one's lifetime, your desires always give you motivation to do better. (pronounces in a sentence are supposed to agree with each other, right?). So it should be: During lifetime, your desires always motivate you to do better.

Just my two cents.
