That made me chuckle, vaguely reminds me of me

(I'm not old, but sometimes my so-called "experience" as a young person and ability to cope with
people feels like it's flying right out the window... usually happens when I'm alone and I let my imagination run wild about people who I
think don't like me and whom I don't like.
ONTOPIC:
As for the WIP, I would wait until you have some stuff put together and are sure you're committed to finishing the game and
then start a WIP. I have plenty of "serious" projects but I haven't picked them up in months because of lack of motivation. I've only just started on another serious project because I have good motivation for this, but I don't plan on starting the WIP until I have made major progess.
I know the WIP is a way to gain support and help, so maybe it would help to start it early on. Then you will be accountable to the community and have more motivation to finish the project. You'll also have people who will hopefully want to help you because the game looks interesting.
Anyway, I'm young and easily distractable, so maybe that contributes to my "lack of motivation" for all the titles I've developed in my head. Whether that's the same for you and/or others I don't know, but that's how I would approach something like this. I know that if I started a WIP for every game idea I had everytime I came up with the idea, I would look like an absolute fool around here

But that's me.
