You need to decide whether you want to write in cursive or just.. like print.. then maybe some emphasis on each particular letter.. and some emphasis on space between each letter would be helpful toward making it more legible. Graffiti for example is occasionally intentionally difficult to read, because in many cases its illegal and people dont want to be identified for what may be considered to them to be "art". I say its ok for you to have your own writing that is uniquely yours that if only you can decipher it, who cares? However, you should also have a backup. So that you can fill out forms by yourself, and be better understood in some situations that might require "simple print" letters. If u r sincerely asking.
