I agree. I would say that civil and/or structural engineering is more difficult than architecture. But architecture is more demanding.
Engineering however has a difinitive answer. Once that answer is acheived the problem is resolved.
However, in architecture getting to the answer is the challenge, and it subjective thus the anwerer is ever-changing (Check Fielder Builders post).
Therefore once you have solved the engineering assignement it is completed. Once you finish your architectural project it only complete when the professor decides it is complete. I have know architectural professors to smash project and make students start over. Thus your 20 or so hours on desgining and building a project are for not and you have to start over.
Time is the biggest drawback in trying to do Architecture and baseball. Not difficulty.
That is why I and Field Builder agree Architecture and baseball is not a good mix.
Anything is doable. Reality- something will have to give.
