I'm just gonna give you my honest thoughts:
You want to make a VN? go for it. Let no one tell you otherwise.
Be driven by your passion and motivations and never be discouraged because there will be trouble, walls, skeptic people,
negative feedback and such. you keep pushing forward and stay strong. Your will is going to fuel the inspiration of many
and people will join you in your endeavour sooner or later.
Why I'm telling you this? Because 1.5 years ago I started this journey the same way you did. Alone, armed only with my
love for VN's and no previous knowledge on what to do. Now we have an established project and our team is full of kind,
talented people driven by the same motivations and towards the same goal.
Don't give up and be true to your goal and your project will never die.
PS. I'm glad you read the resources we have here. They are there to help encourage people like you with the dream of making
a VN. The ren'py guide (made by yours truly) is a WIP and I plan to add more to it when I have the time.
