Thanks to many of you for your kind comments. I am delighted with my progress, especially compared to my disaster years at secondary school trying to learn French. Despite my initial skepticism in either the SSIW method or my own lack of linguistic ability, as I thought of myself, I can see that my knowledge of Welsh is going to surpass my knowledge of French within just a few more weeks.
But to be clear, the stars here are definitely the SSIW team, not me. I am immensely thankful that you have created this fantastic method of teaching Welsh, and I am confident that if I continue following the instructions, I'll succeed.
