here where I am over thinking is a learned thing. when children are in preschool elementary school, jr, high school and even in college they are taught to do critical / logical and analytical thinking.. in other words question and look at all sides of things.

example my preschool child is learning this in preschool when ever they are doing an activity the teacher asks "what do you think would happen if......"........" we dont hit we use our words can you think of other ways to tell someone you dont like something".... "how do you think the other person feels when you ......"

my elementary school children are learning more advanced thinking through their math, science and all that..... teacher puts them into groups and each group has to work out a problem looking at all different elements in the problem to come up with their own answers example the children have a group of shaped blocks and need to think and rethink and think again to come up with so many different solutions to the same problem.

in other words they are learning to over think, not go with just any old answer, to look at every single detail and come up with more than one solution.

sometimes I cant help but smile when my daughter comes to me with her homework and says "mom I have thought and thought on this so many ways it doesnt make sense any more like saying ice so many times it doesnt make sense." I tell her thats when its time to take a break, to let her mind rest for a bit then go back to it, it may make more sense later.

my point maybe trace its time to take a break, then later what ever you are working on will make more sense to you.
