Kimberly, nobody is laughing at you for watching videos! What people are saying is that there is a "WHOLE" lot more to taking a tree down than watching a video! You can learn everything from building a bird house to kangaroo wrangling, That's all, there is many variables when dropping a tree, "especially" next to a house!
I would like to have seen the stump and another camera angle. However it appears to me there was way too much weight towards the house. He was wailing for all he was worth on the wedges with no apparent effect. Eventually the hinge broke prior to the tree starting to fall so it fell off the stump in the direction gravity wanted to take it.
Get to thinking about it, trying to wedge a tree over that has rot or hollow would be a fools mission too. I guess in my mind there would only be two relatively safe and reliable ways to do a wrong way leaner next to a building...piece it down, or get a line on it...
When it comes to videos, I have found that they can be useful. After I spilled a soda on my laptop I found a how-to on replacing the keyboard. That encouraged me to actually go buy a keyboard and try it. That was a few years ago and that replacement keyboard is still working great. Try a tough fall with no real world experience, I don't think so but it is a starting point to start gaining that experience on the "easy" ones.
