XNA...

So, I started to work with C# today with the XNA framework (focused in game development), this is a whole new level to me, so different from what I have been doing until now. I feel excited, but at the same time overwhelmed because I have to learn a lot of new things, so far I have only done a tutorial and was only following what it told me to do (most of the times I watch/read and adjust to what I am doing), I felt the difference between the Object Oriented Programming and what I was doing, hopefully it won't be that hard, but I feel that it will be, and if not, at least it will be a lot of work.
