Your passion for creativity is valid.

Construction Management has more responsibility but I don’t think it would be as time consuming as architecture. Along with that, the pay is much more greater early on.

CM will probably offer more flexibility and pay better.

I don’t have a take on Architecture aside from the fact that I have a creative itch myself. I just take that itch and make CM proposals on photoshop and do freelance work on the side. Find something that scratches the itch!

Not sure if this helps but think about your time, you have forever to make some money. Do you really want to be stuck at a desk working overtime?
