Creativity and keeping ideas secret

Just something I replied to someone struggling with making videogames.

Make the game for yourself. Never mind how it looks to others, it's your game, your expression of you (you are your [gaming]preferences). The artist decides what is on the canvas, no one else. Implement ideas you like from other games what and discard the things you don't like. Play your game, make a game YOU'd like to play. Play it over and over again, to see what it needs and what it doesn't. Do it for yourself, do not try please any other demographic besides yourself.

Another mildly relating thing is what I can only call as "motivational energy"

Let me explain it a bit:
So I assume you've had at least one secret in your life. Keeping it has felt like a pressure inside, right? Alright, what happened when you shared this secret? You felt a bit easier, correct? Like a weight(pressure) had been lifted off your chest? So can you wrap your mind around this ridiculous idea that it is a form of energy and you are releasing it in the form vocalized stuff (i.e. words)? If you can, that's great, because ideas are no different.

You have an idea inside, creative energy some new age buff might say. Now how would you want to release this said energy? As the actual project, or just words about it. Will you manifest your ideas as audible sounds or as the game you want to make?

To put it bluntly:

Do not let the air out of that idea by talking about it.
Less words more action.

Btw, have you ever seen this trope of artist covering a painting that is incomplete, only wanting to reveal with when it is finished, like it was a SECRET of some sorts..? Maybe there's a reason for this.

Also a tip from /r/gamedev make something playable as soon as possible. Perfectionism will cause you to never get anything done. You can polish stuff later.
