Sure your right - Allmost everybody is potentially good Aikido students, and the only way to find out what Martial Art is the right for you is to start practicing. Off course it's a good idear to do some research before you throw yourself into the hands of any instructor or teacher but eventually you will have to begin practicing and it is only then you will begin to develop a true understanding of what kind of MA is right for you. I tried out two types of karate, kendo and nin-jutsu before I found Aikido and for the first time really felt at home within MA.
It sounds like you have the right basic attitude towards Aikido - now go find a dojo where they teach a form of Aikido that corresponds with your beliefs and values on a personal level.
All the best wishes in your search towards the right path.
