So, we have a 83 years old who states "I started to develop an app" and we have a 82 years old, who invested time and work to learn the digital world. The 82 earn my fullest respect. The 83 years old not.
.. it's not you, silly, that's the other guys doing the work for you. So be modest and say at least "I had an idea and got someone who is doing the work"
