Hearing testimonies from different sources, I can only conclude that "You don’t need to be rich to invest, but you need to invest to be rich." Riches aside, investment can increase your financial freedom, but the problem with most people is procrastination, they want this BIG capital to invest, but it is not like that.
Investments, no doubt has been proven to grow wealth. We shouldn't forget in a haste that, as investments has its rewards, there are also risks(sometimes really crazy ones)attached and you could as well lose your money as quickly as you could blink your eyes.
I would say the major problem on why people can't invest isn't procrastination, rather, it's simply cause there isn't any money that is kept aside and can be used for investments. When you haven't got anything saved up, how/what would you invest?
You don't have to be rich to invest. That's true. You also don't want to use all you've got to invest having little to nothing to fall back on while waiting on your investment to yield profits(if it does)
