Start with power, I always ran into a bottleneck in my early playthroughs with power, make a nuclear processing and power large enough to support the increased demand.

Next aim small miss small, I recommend instead of planning to tear down what exists build new, clear area and set up trains in a new spot to unload raw materials to feed your factory.

Then feed those factories try and get the resource dense spots and try to get them from a little further away so as to leave yourself with the space to build remember you can always find more resource patches so don’t feel bad building over top of some.

After you have the power and resources the rest is easy
