When Learning anything Weather it be Guitar or Building Houses Its Better To Do a Child? With the whole "The Mind Is a Sponge"

I find i have a harder time Trying To Learn as an adult and maby that comes from the time i have these days then i sued to have then again i never had much time on my hands...Is there any real Good Way To learn weather you are a Child Or An Adult?

I have never realy had lessons and there for i just played around on the neck. Strumming Patterns and so on..I find myself always playing the same old Riff I have Tried To Create..
