Sometimes you don´t have to be professional to be able to perform your job perfectly. I don´t know if you will agree with me on this statement but I think it has been proven many times by people. Let us take a look at music, for example. Many of the musicians that are admired nowadays and that made a great career, have never went to music school. That is not obligatory. Someone can have a natural talent or just be determined to achieve his goal and that is why he or she finally succeeds. That also applies to other disciplines of our life. Very often when something is broken in your house and you call for help, the person who comes to your house isn´t a professional plumber or electrician. He might have gained his knowledge form his father or just like to do it and through the years he got the experience needed for this particular task. I have recently seen ad of amateur android developer uk. He openly states that he is not a professional but is really interested in this system for mobile phones and that he is able to repair almost everything connected with it. He can also introduce new features into your system and they can be customized to your needs. I think that such android developer uk might be even better than the one who works as a professional developer. What do you think about it?
