Struggle vs Effort
One of the things I keep coming across is the feeling of hopelessness that comes with studying at higher levels when things don't come right fast. We're often used to being able to learn, understand and master stuff fairly smoothly, so hitting a topic that JUST WON'T COME RIGHT! (For me it was Costing!)... it's painful for us.
Take a look at this... it comes from our belief in how learning SHOULD work... which isn't actually true... but it's what we KNOW!
