investment is one of the best ways of reaching an steady income. but you need to be extra careful where you invest. if you can actually find something profitable to invest in, then you can make a good amount of money steadily.
for example this investment can be in your own business that you start and by expanding it you make an steady income over time.
Having your own business is the best way cause you will never be scam rather than just trusting your money online. However, you need to raise a decent capital to sustain your plan and if you have not steady income yet then working online is the best way to start earning.
I also believe that having your own business is the key to have a steady income. But before engaging into any kind of business, make sure that you know your business and it is your passion because you will not be able to sustain it if you don't like it in the first place.
