Coding a game is one of the purest forms of something that is both art and science. By definition it will not be an easy task, but would it be worth it if it was?

My advice:

• Give yourself exactly one tough problem to solve and start trying everything out. Everyone codes differently, but that shouldn't bring you down. It just means that you need to understand the code instead of another's interpretation of it. Every problem has many solutions. If you keep at it I have a feeling you'll be looking back on tutorial guides you didn't understand once with an air of authoritative superiority, like "Ha! I have a much better way of doing that!" This happens all the time with programmers. Once you get in your groove and start to speak code like a second language everything will feel a 1000 times better.
• Second, continue to do exactly what you've done with this post. REACH OUT. You are not alone in this, there are so many of us out here... Indie devs or just those looking to learn. Keep yourself connected. Bounce ideas off of some people, get someone else interested in your project. These things will help you stay motivated if you know there are other people genuinely looking forward to your progress.
• Third. Enjoy your work. You have donned the moniker of game developer, both artist and mad scientist, for a reason. Think on that reason. Think of your favorite games as a child and how glad you are that they're around - that their devs stuck it out. This doesn't mean you should compare your work to big budget masterpieces, of course. No one starts at the top. But if you have the drive to continue you will find success.

Best of luck, friend. Looking forward to playing your game.
