Agreed with everyone else. Plus I’ll add my own note: you will find that your ambition needs require - or are at least made much easier by - progressing other parts of the story.
I really have to have a pretty advanced lab to craft some weapons that I need, for example. (Not to mention the several thousands of echoes in materials, well beyond me for now.) I needed to get to Parabola, earlier. And well before that, a ship was vital - which meant POSI, and I recall that seemed quite costly. I sold almost everything I had to buy a fancy suit.
Now I have 3 parallel steps to take for my ambition and I’m pretty sure I’m going to get to Paramount Presence first, as well as at least halfway to hell on the railway. There’s some really interesting and fun content up that way.
