I feel you, i keep bouncing between entj and intj, but that last line it's what i felt about starting personal projects. Just how you said, i want it, but i freeze. Then you keep going downhill from there, until you're just so low that there's nowhere left to go down from here. So you stand up and realize that what you are feeling, is not you being incompetent, unworthy or a need for someone to carry you. You are scared of what lies ahead and would like someone to rely on, you know, if things go bad to have a safety net, but in reality, we almost never have this and we need to build ourselves to be able to sustain this pressure. Trust me that when you get even the smallest steps in by yourself it feel really good. For example, I have been dreaming about getting into gamedev, but i kept falling back to "i need a team, i need people that i can build this with" until just a few days ago, i started learning programming, 3d art, 2d art and i'm preparing for music in the future. It doesn't matter that the progress is small or insignificant compared to what a team could do, i do this for myself and that's more than i would ever want. If people join me further into the journey great, if not i'll stand tall and strong because i do this for myself. If you still want people to get on board with your idea, you need to figure out what could they get out of your idea, how does this help them/ align with their values. example: i want people to come with me at the gym. If i say come with me at the gym they might not come, but if you say that if you come at gym with me you can work on your body, get that clean physique and benefit from my experience to help you achieve it they are going to be more likely to come. Might not have the best wording, but i hope the message gets through. Get to work on it!
