It's common to feel a bit overwhelmed when starting up something new, especially if that something new is a very radical approach from what you're used to.
There can be quite a bit of reading just so you feel like you're caught up and ready to start.
If you're feeling like this, here's what you do. It's simple.
TAKE ACTION! :)
Just follow the Quick Start guide here. Then, after you get going, take your time and read through the materials at your leisure.
This way, any questions you have will be based on the actions you've taken, which allows us to give you better answers :)
Plus, the material you're reading (and listening to with podcasts), will start to make more and more sense.
Remember, the cure for overwhelm is always ACTION.
ACT, then ask, act some more (!), then ask... it's the only real way to clear out overwhelm and confusion.
And the only way to prevent "Failure to Launch"... is to LAUNCH :)
