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.
From real estate, stocks to crypto, we have seen people buying their assets that were deem worthless, but suddenly became their source of wealth. I remember someone who couldn't afford a land at the city center but wanted to invest. He bought it at a rural area where he could buy over 1 acre. Not long after, the government decided to build a Federal university in that locality. Right now, a plot of land there can buy a plot of land in the city center that he couldn't afford, that is the power of investing.
It mustn't be convenient, it mustn't be in thousands of dollars, a little that is being consistent about and carefully thought through could make that wealth. Start investing today.
Whether you know it or not, if you've been paying into any kind of pension through your working career then you have been investing in one form or another. Many pensions will be staggered so they go heavy on equities (stocks) early on in your life and then tip towards safe government bonds when you are preparing to retire. Pensions often become one of the biggest assets in our lives and compound over a long time, so why not do something similar where you have a bit more control about when you redeem it? You will honestly open your mind massively if you read a few books on finance and maybe prevent anyone taking advantage of you in future in areas that you don't know anything about - it's very straight forward most of the time, you just have to find guidance described in a way that makes sense to you.
