1.  Finding my way around.
2.  First week I was used to something very familiar, the U-bahn.  if felt safe and secure using the U-bahn.  I did not want to explore or find because I get easily flustered.
3.  The next week I felt more secure using the U-bahn.  The repetitiveness made more security (since the break (7 days long-I used the street car and got to know other source or transportation).
4.  The repetitiveness.
5.  The attitude was confidence be like an Austrian native.
6.  The prediction will be usually the same yet more aggressive.  That is, I'll want to be confident before going out to use other means of transportation.  Once the confidence is set in, I'll be aggressive enough to seek those other means of transportation.
