There is an event something making me feel upset

Today the project I've been working on make made me feel upset. I think I put a lot of effort into it on the project, however I did not meet the deadline (or could be "did not achieve the result I was looking for". The first means that you didn't complete the project in time, the second means that you were dissatisfied with your marks).   arrived the milestone.
That'a because I put myself on the wrong direction.  That's because I went about things the wrong way.

Anyway, I should think look on the bright side, I have still practiced a lot, I still managed to get in a lot of practice, so I'm on the right track. I'm just on the road.
