For most people, the bulk of the capital to even begin investing comes from paid work. If you don't even have a proper salary yet, you shouldn't even begin investing. Focus on getting a proper salary first. If your salary isn't high, then invest in yourself and get yourself to the next banding of pay scale. If your salary is low, no matter how much you scrimp and save, you're always on the 1st gear and can't really accelerate your path towards financial freedom. Saving 100% of $10 is not going to beat saving 10% of $1000, so your limiting factor to reaching financial freedom is not your investment power but your salary. You'll find that spending time and effort to increase your base salary will work more wonders and than relying on investments,unless you're exceptional. But everyone thinks they are exceptional and not average... I think it's much easier to increase your salary by $100 per month than to increase your passive income by $100 per month.
After you raised your base salary to as high as it can get, then look towards saving a greater part of your salary. This first tranche of money is going to work hard to bring in future streams of money, so make sure that you can save. If you can't save a significant portion of your salary, then maybe you should concentrate on improving yours savings percentage first before you think about investments. Get the basics right and build up the base for your investments to work. Also work on reducing your expenses. Increasing your savings is really just one simple equation : increase your income and/or reduce your expenses. By increasing both your income and reducing your expenses, you will be able to save exponentially.
Once you've done all this and set aside some money for emergency funds, bought some insurance and budget aside some cash for near future spending like marriage, housing and renovation, then we can start to talk about investing. In summary, before you start investing, maybe you should invest in yourself and work hard to see if you can increase your salary first. That is more likely to be safer and surer than any investment you make in the stock market.
