Hit the road without delay.

If you want ("one wants", while in speaking people will say "you want" "one wants" is actually correct unless you are talking directly to someone/a group of people) to do something, don't be hesitated ("one should not hesitate" "then don't hesitate". So I decided ("therefore") to go to Golmud the next day. Since never having been there ("Since I have never been there", "Since I have never been there before"), I inquired of ("I asked") some friends working in travel agencies about the route. After ("After being told"/"After I was told")told that there were no direct flights to Golmud, I decided to transit at Chengdu Shuangliu international airport.
