I'm very impressed by your results and a friend and I have been taking your advice to heart for the last 2 months and working on learning and creating our first app. Our programming experience is very limited but we're making progress. Great advice and interesting to see your results.
I have been learning Android Development by creating my first app that has been published on the market. It is not too popular but learnt me a lot about development and good marketing appeal. Most important is to do something and try hard to do it well and the success usually comes sooner or later ;)
