Intensive 3 days training - First things first

Just finished an intensive 3 days training - First things first by Iain Ewing
There were sessions of doing presentation, classroom lessons of the technique, followed by presentation again and classroom lessons of knowing personality of myself and others .
So we can see the difference of each of us of 'before' and 'after'.
I need to mention that the trainer, Iain Ewing is really 'charming' for us. He gives skill and knowledge, and enable you to realize the effect of the 'change'. It made impact to my mind of making changes in the near future.
On the first day of training, I worked until 03:30 at office to prepare the group presentation with Almen and other member as we were not getting the data easiliy and we took time to prove our logic calculation. I kept asking myself 'Was it worth to struggle so much time, while other people already went back?' I was frustrated.
On the second day morning, I have told myself ' forget about yesterday and enjoy the day of training and learn as much as possible'. I did my best and got good comment in the rest of the training.
After the whole training, Almen and I went for dinner together and shared a lot of thought about the training which gave us so much fun and inspiration.
