Translation of self-opinionated in German

I hope you you had a successful week in Dortmund. Because of the bad weather at the last moment I could not get on my flight to Dusseldorf and I have stayed home. I was afraid to fly.
As mentioned in our conversation, I will send a more detailed description about all the other exercises. As indicated previously, I believe in your technical skills and in your talent.
Right now I'm looking for a new job. Actually, I feel good, although I've had a cold for a few days. I can not get past autumn without catching a cold and I cough usually until spring.
