Why am not able to get a grasp of PCB designing?

I am trying to design a powerbank myself. This is my first electronics project.
After completing the schematic and deciding on the components with a lot of help from this forum, I started working on the PCB Layout. I watched many videos but I just couldn't get started. Idk why.
I just get blank when all the components gets populated with the messy rat's net. The datasheet has given some layout rules which I am not able to follow.
DAE felt the same when you started? Do you have suggestions for resources that I can start with?

I wanted a rude username:
Set yourself a series of tasks.

For the first task, just push and rotate stuff around until the number of connections that cross each other is minimised. Don't even worry about being restricted to a board size/shape or routing any traces at this stage.

Post a PNG of your layout at that point and ask for guidance on meeting the design rules.

Make mistakes.

Thanks! I will try doing it and post the png

My method is to break any design down to chunks, e.g. this is a charge IC, it has X number of components that belong to it, so lets group them together and lay them out as best I can, Then the next group, and so on,

Then after they are all grouped up i start connectiong up and positioning those chunks

This way you never have to try and take the entire project in your head at once, Its always smaller and simpler chunks, It also helps prevent routing yourself into a corner as it usually results in the least connections needed between chunks.

Thank You.

The component I working with is a SOC, so all the components in the schematics are connected to it. Is there an option to selectively populate the PCB from the schematic? May be I can try breaking into blocks and layout in groups
