It's interesting the fact that we as humans are subject to 'habituation' in pretty much everything we do, we get accustomed to our current circumstance and our emotions pave one way or the other in relation to that habitual baseline we call lifestyle. 

Relating it to this post, it is quite fascinating how upset we in the western world can be due to a simple coffee spill as you mention. But like you do by writing this post, I think its important to shed light and give perspective on things, because first when we can identify a behaviour, we can correct it. 

Otherwise, if you're into travelling, vlogs, fitness, self-development etc feel free to check out my channel, in any case keep up the good work and I'll see you around! :)
