Every Investor including Ray Dalio and Warren Buffett have one major investing problem and that is cash flow.
The first time I invested, I invested $100 but now if I add $100 to my portfolio it will have a negligible impact. Even Warren Buffett has this problem, although he was able to increase his cash flow through insurance and reinsurance, now he can only invest in big companies to have any effects on his portfolio.
In order for you to increase your cash flow, you'll need to increase your income, maybe by starting a business or through a high income skill. For example, I am a high ticket closer and this is my main source of cash flow right now but there are limits to this, so you should always be thinking bigger.
