Thanks a lot for your reply. When I try to solve a problem I generally see the output needed and construct code to get the pattern with a lot of trail and error. I am not sure if I can scale with this. If I am fresh and in flow I can come up with good solutions. If not and I am nervous then I will have trouble solving something as simple as fibonacci. I sometimes have trouble doing pattern matching where I get confused if the problem is changed slightly and is made tricky. I think this is because I am trying to be too specific with the match and not seeing a generic picture. Can you suggest how a person with a job can practice so thoroughly? 8 hour sessions everyday is tough maybe on weekends but still is sometimes difficult.
