I was reading this advertisement about an upcoming event that would probably attract people who work work in a particular industry as a well known decision maker in the field is scheduled be a guest speaker of sort. In that sense, anyone who is remotely involved in the field would probably want to get to meet the person. As expected, the price seemed pretty hefty too if your sole intent was to try and expose yourself to the individual.
If you are actually going to learn and network with others then I suppose it can be a good investment. I think it is kind of irrational to believe that you can pay for an event like this where whoever the hotshot is will simply be your saviour of sort in terms of giving you the opportunities that you are looking for. Most likely you would continue falling into a cycle too of paying for events like these and just frustrating your wallet in the end.
