Duties of a Software Developer Fresher to improve skills

Sir,
My name is Nathan from Kerala, currently working as software developer at Calicut.
I  have got a six month training  from a company and currently working in a company as employee from January 2014.
The skills I using are c#, asp.net, sql server 2005/2008, AJAX, CSS and Crystal Reports.
I am actually confused of from where to start, what do learn and where to focus?.
I know that the next One Year is to learn, but doesn't know that starting point. Please tell me the advice for my problem.

Currently working with Windows Application form.
