You do not need to put money into your own bank account. It's an automatic consequence of the above actions. The task is to perform the above actions, which are one stage removed from the money. Your money problem is solved.
Note that the money does not appear immediately but at the end of the month. That means it has to be earned, and whilst it's being earned, it's not yet visible to you, but it is accruing.
With Step Three, the commodity is happiness not money. God is offering us a job. All we have to do is show up, do as we're told, and not make a complete fool of ourselves, for instance by interfering with other people's lives or arguing. Magically, at the end of the month, happiness shows up. Not instantly. But it's on its way. Your happiness problem is solved and is no longer of any concern: the only thing that is of concern is the job.
When you go into work, you ask your line manager what to do.
With Step Three, it's as though you won't yet have a direct line to your line manager. Your security pass does not yet allow you onto the floor where your line manager works. However, your colleagues do have a security pass for the management floor (because they have completed Step Nine, the reward for which is the security pass for the management floor, where they have direct access to all of the line managers). Until then, therefore, you have to rely on a few, carefully selected colleagues for advice on what your line manager wants you to do. The line manager has indeed sent you a few memos and emails, so you're not completely clueless, but you do need others to provide their experience to fill in the gaps.
To be safe between taking Step Three and completing Step Nine, it's a good idea to have a bunch of people around you who have plenty of experience communicating with the line manager, or Higher Power, to help formulate safe and sound plans for the day and make any ad hoc big decisions until the relationship with the line manager, or Higher Power, is fully established.
