Well this is a really subjective question for the simple reason that everyone has different opinions on every topic. Personally I think that to be a good architect you need to be really sensitive about things arround you in every aspect, because as an architect you need to be able to provide things that are aesthetically pleasent, friendly with the enviroment and most important to satisfy people's needs.
You also have to be really responsable as well since you'll be in charge of a huge project that could affect people's lifes dramatically.
One of the most important things is to be hardworking because being an architect is not easy, you need to consider a lot of things when planning something like what is the point of the final project, is it safe, how long it will take, etc. which isn't easy and it probably will take a lot of time.
Also you will need to be really organized 'cause you probably will be working with lots of things at the same time and you will have to be really good at managing because you will have a deadline for the project and you have to finish it on time.
another important characteristic is to be really creative, since you'll have to solve a lot of problems the best way possible a good imagination will come in handy.
In conclusion for me to be a good architect you need to have a lot of different skills that will make you a better professional depending in the area that you want to work.
