It takes practice, just following a guide isn't going to get you results instantly. Drawing isn't assembling a desk there's more to it. Keep playing with it, keep a loose grip on your pencil and just make lighter looser shapes and then detail it up and eventually something will come out of it.
This.
You will find that many people out there are good at what they do because they constantly do it and truly enjoy it. It's fueled by a passion.
Sure, there may be that initial spark of talent where you seem to just be good at it, but that spark doesn't always happen initially. When I first picked up the guitar, I was terrible at it and didn't pick things up quickly like I did with the drums, so I dropped it. Then a few years later, I dusted it off again and although I still sounded terrible, I slowly got back into it, and my interest and skills grew exponentially. Now I really love it and play all of the time, people are surprised by my progress, and I'm even starting to write songs.
I don't know if it was that I gave the guitar more of a chance, or that I was mostly just messing around and having fun at first instead of expecting instant-gratification and rapid advancement, or maybe in those few years I grew musically from playing the drums and exposing myself to many, many new types of music, or maybe it was a combination of all of those things. My point is, don't just put a particular thing off just because you aren't good at it at first. There are many subjects and activities I thought just weren't for me a few years ago, but now i thoroughly enjoy and am actually pretty good at.
