I was thinking yesterday. What if I made a huge mistake? 

Actually I was overthinking. I was thinking, Oh crap did I just ruin the whole of my future. Although that was an exaggeration and I realized that today. 

Psychology. Why... why did I do that? Because I enjoy the subjects. It's biology and statistics and writing and more grey areas than facts and that appeals to me. It is thinking and questioning. It seems interesting. I picked the subject because I though I would enjoy it. 

The problem is that now I am thinking of it in terms of: will I get a job in the field? What if I go into medicine after? Wouldn't those three years have been a waste? What if I end up working in TESCO's? How will I look after my family? Will I make money?

And it really sucks that I am thinking like this. But realistically, doesn't this world revolved around money? Could a person honestly say that they didn't care about money at all or anything materialistic?

I personally don't think so. 

So the question is ultimately, do I follow my heart and do something I love? Or do I do a degree (like medicine) that had a pretty much 100 percent graduate prospect?
