A big part of any learning curve is to investigate how others have gone about achieving your aims.
If you have a fixed plan for all aspects of a project you have concieved and find that when you ask for help in getting it to work you universally get suggestions for alternate designs it's either that no-one understands or its that they do understand very well ;-)
