Source Filmmaker -- oh, where to start with the flatter? Initially, I found this program absolutely complicated, confusing, and I was skeptical about using it. I would give up constantly, and say, "Man, I can't do this!" It was all a bundled mess- until I watched Valve's tutorials, fan tutorials, and inspiring videos made in the program itself. It took me months to figure out how to use the Graph editor. It looked complicated at first, but then, I learned about the bookmarking technique. I then learned the very basics of Source Filmmaker, yet I still continued to doubt myself. I wanted to quit. I wanted to say, "That's it; I'm done with this program." Then, I told myself, "No, I can't give up. Animating is such an accomplishment." I watched the SFM videos people made; and that's when I developed my animating style. I have spent nearly 500 hours in SFM, and for most of the time, I practiced, and practiced, and practiced, and I wouldn't stop until I was satisfied with what I animated. Ladies and gentlemen- don't EVER give up this program, because once you're adapted to this fun world of animation, you won't ever have to worry about failing in it. Give this program a go.
