Roger, you just gave yourself the opposite of a pep-talk.
Do you need others to encourage you towards the answers you already know? Put on your game face, respect yourself enough to grow your confidence since every freaking human has the same approximate number of brain cells and the same infinite level of potential awaiting them. You have already made the biggest step of acquiring the technology instructions. You know that many here posess what they have sought after and you know this simply also applies for every other human on earth, yourself included.
Get back to the system, realize the amazing potential that awaits you. Stop talking towards things such as "depression", this is an illusion and the sooner you realize this as what it truly is, you will become the Roger I know you already are.
Do it. Confidence + Desire = Results, and remember NOTHING in this world or the next can stop the man with the right attitude of achieving his goal.
