"Stay at home, don't go anywhere" [I've put these in quotation marks because you're quoting your friend]. 

I like to travel alone and I really enjoy it. With more freedom, you can schedule everything as you wish and you can make friends on the trip.
But one of my friends doesn't think so agree and he thinks it is not safe.
He said:" Just stay at home, don't go anywhere, you see, the plane can be disappeared, the ship can sink be sank, people get kidnapped, and so many other horrible things can occur...Just stay..."
He may be right, but for me, some things you want to do, you have to try your best to do the things you want now.
If there is somewhere you want to go, just go, because you won't know that if you'll still have a/the chances or not...

Good job Luer! Well written.
