The dark truth about attending big conferences

In 6 days, London Tech Week will open, and I will participate in it. Do you know what thoughts come to my mind? It is exciting and worth visiting from the point of view of obtaining new information. However, there is another side of the coin – participation in such an event creates a lot of stress and tension. I don't like such things because it's very noisy and chaotic, and there are thousands of people, some short, meaningless communications when you forget the names of the people you just met there. From the network's point of view, it was always tough for me because you feel like an ant in the middle of a metropolis, and you have to have a particular type of character when you are ready for this kind of event, as I think. So, I am attending it to take a piece of pie with the new information, but on the other hand, I am very well aware that I will need to accumulate my energy to hold on during these days. And how do you feel about such noisy big events?
