You will never be able to do it...
Read some worklogs and see some of the problems peoe run into for not reading, not taking their time, assuming/guessing, being stupid, and also not having/using the right tools...
Here is a quick test for you:
Can you picture in your head how to build a circuit to light up an LED??
If you cannot imagine how to make this off the top of your head, then you are in over your head and should not be using a portable GC as a first time learning project..
Unless you have about an extra 1000$ to spend replacing all the parts you burn up / blow up..
