Some time I am so grateful that I'm one of those who are able to view a lot of things in life realistically. Some other time I just feel like a douche.

Example of a benefit:

A cute guy is eyeing you from across the room.

You applied for a job. There are 50 applicants and you are not likely to be in the top 3 most promising candidates. Realist goggles on, you are likely to do way more work and get lots of practice and even ask around bits of advices. Hence, you are more prepared and increase your chance of landing the job.

Example of a drawback:

A person you know is going out of his or her way to really make your life a shit whole and he or she is a smart manipulative bitch. By you I mean me and by he or she I really mean She. After a few serves of nonsense, it's pretty obvious to me. But according to people around me, shit is normal? It's although their mothers and fathers took them to get these shots when they were young so they grow immune to all this bullshit and somehow my parents just forgot to take me. It's like we took a weekend trip down the bush and I came back with this X-ray vision (it's not my fault I didn't take those shots!).

Story of my life.
