Change!

I think for many people it is extremely difficult to accept change. Change in how they think, how they do a certain task.

Once a famous man said you can't do the same thing and expect different results. Or sth like that. 
As a result I can say that we cannot make something right by doing something wrong. 
It just makes it worse.

So in order to find a solution to a problem we have to look at other angles. Going along the same wrong path over and over isn't gonna pop out any better results.
