We have a problem

So, I was thinking today, one of my skills is problem solving.  Part of my job requires this, but it's not simply occupational.  I enjoy solving problems.  That's why I enjoy mechanics and hacking computers.  So problem solving is a hobby for me, I love to do it.  The issue I have with it, is to solve a problem there first has to be a problem.  For someone that enjoy solving problems that means I am always looking for problems.  When you look for things you often find them. At least more often than if you're not looking.  For this reason I think I tend to be negative.  Negativity generally surrounds problems you know.  So if I'm fixing problems, I'm in and around problems, the problem is I will be in close proximity to negativity which will inherently rub off.  So now I have a very difficult problem to solve. My problem, if you haven't already guessed, is this:  How do you become a positive problem solver? Or is my problem with negativity simply circumstantial or genetic? I don't know, but I hope to one day figure this out.
