Take your time writing it out, and practice practice practice. Check out other peoples style of writing and try to copy their style of hand writing. I'm a guy and I managed to fashion a style of hand writing that closely resembles some women I know. Might sound a little funny coming from a guy, but neatness and style mean alot to employers.
I recall in grade school 50-some years ago they kept examples of beautiful script at the front of each classroom, above the blackboard...maybe they still do?
But yes as others have mentioned, to look at handwriting you like and just practice.
Computers are SO handy now, so wonderful for letters and other types of composing. Nevertheless in personal life also, as well as for employers as TRC has mentioned, there are times when a hand-written letter to someone is just so precious, nothing will take its place.
Just take you time and and practice a lot and you may end up like me I can write with both hands and I have five different styles!! But like I said take you time and practice and you will do just fine!! Good luck!!
I used to write in print but then I didn't like it because I wrote kind of sloppy. So I got interested in writing in cursive and I can perfectly write with it. My folks, friends and teachers give me alot of good comments on the way I write. So maybe writing in a different style might work
