Grammar, Usage / Unintelligible Lyrics [3]

I've got lyrics quite not understand in some songs. Here they are:
<EVERYDAY > from High School Musical
'Once in a life time, means there's no second chance...'
Must he repeat the same meaning again?
<PRETTY BOY>
'Never ever loved no one before you...'
So many negations that I can't really figure out how to rationalize the meaning she wants to express. But everyone can be sure about the meaning "you are the first one I love'

<NEVER HAD A DREAM COME TRUE >
"One regret from yesterday that just seem to grow with time"
What 'grow with time' ?
<GOTTA GO MY OWN WAY>from High School Musical
'W might find a place in this world someday, but at least for now, I gotta go my own way'
What kind of place does she want to find? What for?
<SOMETHING NEW> from High School Musical
'Living in my own world, didn't understand, that anything can happen, when you rake a chance.'
I can't understand what kind of relevance on earth are there between the 4 sentences.

Writing Feedback / My best friend in elementary school; Friendship forever [4]

My best friend in my elementary school phoned me today, saying that she had been admitted to Northeast Yucai high school. So we will be together again after such a long time's apart.

We talked a lot, recalling the close feeling we had had. But some of her words really hurt me. When we talked about my going abroad, she just said 'Do you think you can go out?'. She also asked so when I talked about my JLPT 1 as 'Do you think you will pass it?'

Maybe as a good friend, I must consider these as a kind of...greeting, or concerning? But there is a meaning of despising, or worse, being jealous, isn't it? And when she asked about my private things, such as grades, as I'm modest, I didn't tell her the truth to avoid being regarded as showing off. Now I'm regretting about that. She may believe that I'm concealing my 'bad fact'.

I'm narrow-minded. I told myself: just because she didn't care about my feeling of being asked that, she treated me as a real friend. In this case, she won't doubt my words about myself as we have been being together for a long time. All right, get rid of it.

My best friend will be together with me in my high school life. I'm longing for the military training before the senior high 1.

Writing Feedback / graduation grieves me [3]

Time goes away without being perceived. My junior high lifetime ended by today. Everything which was boring in my eyes now seemed different. We read the summary and all expressed a flow of sad. How many "6 years" will we spend in our whole life? But we're determined to spend this together, happily or sadly. Isn't it destiny?

We raised money for our teacher's presents. 4 monitors went out to the supermarket. In the 3rd class in the afternoon, I raised my head to see our class teacher standing at the door, attired in a new shirt, which I thought to be the present. All students shouted "too handsome". Surely he was, all the time. I can't really figure out what kind of countenance he had. Proud? Happy? Satisfied? Showing off?

It reminded me of his having said "I'm longing for your departure as soon as possible". According to Sabrina, one of the monitors, described the reactions when other teachers received our presents. All happy, no exception, even those who said unpleasant words of us. I think no matter how troublesome we felt, the bad feeling will disappear when we leave each other, only with sweet memory remaining. Let's treasure this time in the following 3 years.
