Is there anything John cannot do with his skillset?!

There is probably loads of things that all people cant do because they are human! It is not all knowing everything. The more that is done, means the things you don't know or haven't tried can all be learnt, or tried by others! So the best is to keep positive and look for the light and the best can happen! There is always room for improvements to be made! If not then life will be boring!! So it is best to keep trying!
