I was in your boat not too long ago. Getting a job helped. It’s not great pay, but it’s good pay, and the schedule gives me time to work on a project. Live cheap and use as much of that income from the job to invest into a single project, I recommend one that isn’t an invention or new product. If you have a passion for something and the skills are already there to design and produce it, then by all means go for it, but it’s a gamble. There is only 1 musk and 1 bezos, but there are 1,000s of people that were trying to be them when they were becoming who they are.
