Translation of amplify in Spanish

As I have already mentioned in my last email, it is a breakthrough, I have never been so successful. I have visited several Spanish schools and would like to discuss that by telephone with you.
I hope that I will have time to go skiing. Maybe it is even better to go at the end of the season. The doctor, however, did not give his diagnosis yet. If I cannot go I will have to find an alternative.
Do not worry, please, all is well here. I find it fascinating how fast you can write texts in foreign languages. I know how hard it is, and I congratulate you. Waiting to your next email.
