Now lets say your vlogging channel has a lot of viewers and is making a lot of money. You can reinvest the money into your channel to improve the quality of your content. For instance, you can get better equipment or spend more on ads to increase social outreach. Once you get to a certain point where your growth slows down and spending more money isn't going to really give you the returns it once did, I would recommend saving it and investing it for the future. Keep 6-12 months (depends on how comfortable of a safety net you want) of living expenses in a high yield savings account. Put everything else in an IRA (Roth or traditional, depends on your financial situation and expected financial situation in the future) and the rest in diversified investments (bonds, stocks, etfs, real estate).
Don't be a victim of lifestyle creep (If you start making more money, you start spending more money so basically it's like you never really made more money to begin with). Find a baseline and stick to it. Simple example: If you make 60k a year and spend 30k in expenses (rent, food, bills, equpment, etc), then the next year make 100k but spend 60k in expenses, you only really made 10k extra. And what happens when that 100k goes down? You'll be stuck with the 60k in expenses and might be poorer than you were when you were making 60k. Now if you made 100k and spent the same 30k that you did the last year, that's 70k instead of 10k you have to invest for your future.
I admire your ambition and your lofty goals. While there in no prescribed way to effectively become a millionaire overnight, there are steps that you can take to put yourself on the right path towards success.
As alluded to in previous answers, the first step to obtaining wealth is to really understand how money works, and how it can work for you. One resource that I personally find useful and inspirational is the book "Rich Dad, Poor Dad" by Robert Kiyosaki.
It is also important to come up with a plan for how to achieve your goal. It can be easier to break a really large task into smaller, more manageable steps. This plan can and will evolve over time, so celebrate the small victories while learning and growing from the defeats along the way. If you can, share your passion and your plan with the positive influences in your life so they can help, you never have to go it alone.
I wish you the best and hope this answer helps.
