It doesn’t fit in my schedule
Every time I started taking classes, I noticed that after a few weeks I was already lagging behind. Made sense because once I couldn’t make it due to a meeting, I never finished my exercises because I had too much work to do, then to top it off, I had to go on a three week business trip. So, after that, I lost track completely. In the end, I quit, because it was just too frustrating and unrealistic, while I would actually love to be able to do it.
