Let's say you're in nursing and you start a career in tax, something you've never done before and have no knowledge in.
You're given a rigorous programme to get through in order to become a 'tax specialist'.
Would you feel like if you just worked hard enough, put in the extra hours and did all the studying, you or anyone could become this tax expert or (insert profession)
Or, do you believe that some people are just not cut out for certain careers no matter what or will just feel out of their depth and shouldn't feel they have to? Honestly at my point in life I don't think I've got the headspace to train in and learn something completely new and alien, especially something like that which doesn't interest me.
