You should do your touch typing lessons as often as you are capable of without hurting your fingers! As with everything else, regular training gives the best result. Most people will probably get the best result by distributing the lessons to several days in the week rather the doing a lot of exercises in one day. It is a good idea to put your touch type training into a calendar to be sure to remember to do them. If you don't have a calendar you can use the Google calendar which is free and easy to use. In this way it is easier to remember to do your exercises.
The programming community is full of people who are willing to help the next generation of programmers. GitHub, the online hangout for developers who use Git to manage their coding projects, is designed for online collaboration. Not only do developers host and share their projects with their peers, they also provide code feedback and general advice to the community.
The free typing lessons supply the complete "How to type" package. Animated keyboard layout and the typing tutor graphic hands are used to correct mis-typing by showing the right way to type for your learning and practice experience. Lessons' difficulty gradually raises as it starts from only 2 characters and ends with the entire keyboard. When the lesson ends, you can learn a lot from the practice trends: WPM, accuracy and errors distribution.
Take a few minutes (or a day) to think about the reasons—the real reasons—why you want to learn a programming language. Be honest with yourself.
