I didn't know a thing a few days ago about modding but now only 1 or 2 days later I have learnt all of the files I have edited icons, splash screens, music, un-packed files, edited setllement ownership and changed most of the game. Of course I am not expert and need alot of help but I have managed learning myself and if you are willing and motivated you can learn everything so
"What are you good at then?" is a bit odd as you may not know.
