Tone of my writing

I am trying to figure out how to write with good tone. But what is good "tone"? I think i should write with authority, clearity, and academic purpose, but how do i write like that when i am describing my own experiences? The last few times i have written that part of my essay it seems out of place, and it doesn't flow at all. Mabye i need to re arrange the order of my paragraphs so i can make it make alittle more sence. So far this has been the hardest part of drafting this paper
