Most of the time you hear about the time someone won something, very rarely you will hear about the other times they ended up losing, which usually accounts for more than what they won.
You're right, people will only tells you the most interesting aspects of their stories by taking away the difficulty they experienced althrough the process, but i don't know maybe they usually do that to entice others or to push them into having same experience they've been through, i see it that after having both experience on the good and the bad, it is also expected that we take our personal decision base on the level of research we did, people are loosing in gambling but it will not be noised but when they eventually win luckily, the whole gist got aired.
