Your ocular Kekkei Genkai would be the Sharingan.
Out of all the Ocular Kekkei Genkai, you're most likely to have the Sharingan.
This is a generational Kekkei Genkai, yet it only appears to a select number of the Uchiha clan.
No one is really sure why it chooses the members that it does, but the Sharingan is often regarded as a curse, as well as a gift.
With training, the basic Sharingan can mature into different forms or stages, such as the Mangekyo Sharingan.
This makes the Sharingan much more powerful, but also harder to use.
Most of the Uchiha's are rather serious, focused people, so there's a pretty good chance that your personality matches that description at least somewhat.
