This individual helps hold me accountable to the action items I've listed to perform the goals I've outlined for myself (I work quickly and take massive action, so I've outlined goals taking me only into the end of the first quarter of this year).I'm constantly on YouTube looking at different videos on a myriad of topics concerning flipping, financing and real estate in general (usually this is a last resort /exhaustion type of thing.
