It depends on how good you are at extracting useful data from your 'customer'. If you go wrong about finding his/her problem you could be f*cked because it might not be a real problem although he/she describes it to you as one.
On the other hand you are the expert of your own problem so you don't have to worry about the above.
I hate when people suggest books as I hardly ever read books but 'The Mom Test' is an amazing one where you can learn to validate your assumptions properly and learn truly if what people describe to you as a problem is really a problem. :)
