If you want to improve your handwriting, you have to be really determined about it.

I'll tell you a little about myself. When I was really young, I think I was eight years old. I got admitted into a new school. It was a degradation from my previous school (talking about fees). I was happy nonetheless to be in a new school. But not for long.

We were taught Arithmetic and given some class work to do. I hurriedly did mine and submitted as I wanted to make a mark as a very brilliant pupil. I waited for the sum to be marked but what I heard was, "Who owns this fowl-scratch handwriting?" I felt like melting to the floor because everyone had burst into laughter. I felt really bad and couldn't play with the others during recess.

It was from then I made my mind to improve on my writing. Few months later, it just happened that my brother's friend, who attends same school with him asked me to go get something inside their house for her (we lived in the same compound). As I got in, I saw her notebook. My gosh! That was the most beautiful handwriting I had ever seen.

The note was a rough one. I took it and it found its way to my house. I began practicing writing exactly like that from that day. I exhausted many books in doing so.

Also, I began to take writing homeworks seriously (we had a subject called "HANDWRITING" with a workbook where the pupil is expected to re-create what he sees). I would always try my best to do it as accurately as I could.

On holidays, I would finish the remainder of the book that we didn't do in class. I would even collect my classmates own.

Fast forward to when I got to Primary 4. I had the best writing in school and would even get 100 over 100 as total marks (accumulation of tests and examination). I was copying on the board from my lazy teacher's book while my mate looked from the board to copy their notes.

My writing has earned me favors all through my secondary school days. I've gotten used to hearing "You write like a computer!"

All of these happened because I was determined.

The way you practice regularly in writing then you will have good hand writing .before few years my handwriting was also so bad people can't able to read properly and my school teacher call my parents that your child is not writing properly and we can't able to read what he has written.From that I started writing for 3 hours continuously slowly and after 3 months my handwriting comes brilliant and now you can also understand and appreciate my handwriting.

So,you have to work hard to improve your handwriting then only you get success and you can also feel good on reading your blog at which you had written with your hand.

i used to have a bad handwriting some years ago and it could be a terrible experience especially when you are an author or in a field whereby you do alot of writing,my writing was so bad that many of my friends and colleagues do complain about it,what i did to improve my handwriting was to first of all admit that i have bad handwriting,then the next step was that you need to keep writing more and more,the more you keep writing and writing then gradually you will begin to have a better handwriting but you aslo need to be determined and also you need to focus more on yourself and stop bothering yourself about your handwriting because your handwriting should not determine who you are

I don't really know what you mean by "vision", but the most and fastest proven way to improve one's handwriting is constant practice and a goal why you need to improve your writing.. 

I myself used to have the worst handwriting. My handwriting was small and they are written so close to each other that you one needs to take a really good look at it to read my writing. However everything changed when I went to college and have this "Drawing 101" subject in which we were asked to almost always use straight big letters(Kind of like the Times New Roman font). In Engineering, this is quite a must in order for everyone to easily read what you wrote.

Long story short, because of that 1 semester subject of mine, I learned (or was forced) to write in Big readable letters. My goal at that time was to pass the subject and the only way to pass that subject was to adhere to the rules given by the professor. And the practice was a good full semester. 

So if you want to improve your handwriting, you must first ask yourself why do you want to improve it. Are you forced to or do you really want to improve? With vision alone it is hard, as "handwritings" are personal stuffs that no one other than you notices especially in this age of technological advancement.
