Checking prices and dreaming
It's like a big trap for procrastination besides if it makes you move further straight ahead))
Writing so coz saw several examples when people just check price for something they want have but instead to do things that can make them closer to their dream they are just dreaming. But on the other side of hand sometimes it's really needed to dream, set up goals and move on. In this case it can be considered as useful dreams.
It can be a trap, as you said... Trying to catch the reward, forgetting to do the work... In my case, it's is more like a goal and motivation to push!
