I grew up writing and doing most activities left handed. In School though, they typically only had right handed equipment (golf clubs, baseball mitts, etc.) so I suck equally with either hand in most sports. Interestingly enough, when I started working as an electrician, my tool bags were set up with all my side tools on the right and I didn't even think to switch them until a few years after I'd become used to using my right hand for them.
