Writing Feedback / Essay about my life and changes - can you help me? [5]

Hello! I'm a 14 year old boy from Norway, and I'm wandering about if you could help me with my essay here. My english are realy bad, but I would be very pleased if you could help me:)

I won't post the whole essay, in case my teacher finds out that you help me.

I'm only posting some of the sentences, and I hope you can "fix them" to be much better, and correct:) Please change the whole sentence if it's wrong.

Ok. Here we go:

"My life has gone trough several changes since I started(??) the adult-life"

"Ordinary boring jobs, nothing abnormally to happen - only the same habits."

"And suddenly I became a sailer/explorer.??. etc instead of an average american."

"The journey was also well prepared. The idea was to travell, and arrive at one of the uninhabited Fiji-islands. "

"Some wind gusts?? later I arrived at the island."

"The plan was to make a little wooden house in the outskirt of the jungle, so I could keep an eye on the boat, not to mension it was much more save to settle in the outskirt instead of the jungle."

"Not a single cloud appeared, only clear, blue skies"

"Suddenly, as I stood up after drinking some water, something appeared among the trees,"

"Several of hours had past since I walked into the jungle. The weather changed, the temperature was a bit lower and it become darker. I gathered some leafes from the huge palm-trees, and made a bed in my wooden house."

Thanks a lot for your attention. I know my english is very bad, but I hope that you could make it a little better. I realy need your answer before 11.00 tonight, because I'm handing in at 23.50.

Thanks again:)
