Social media has helped me immensely. I use it every single day to source sales leads who can then become clients.
In the initial days, I used it too much without any focus in mind. Once, you really start to study the system and how it can be beneficial to you, only your imagination is the limiting factor.
However, before you jump on the bandwagon anticipating millions in income, be forewarned, it takes years (literally 2–3) to make a solid following and then get the numbers to benefit from.
Not only does it take years, you also have to put out stellar content and engage with your audience. This cannot be left to automated tools.
Today, I would say, a bulk of my sales leads (perhaps as much as 50%) come via social media. I cannot function fully without it (if I were to drop it / stop using it).
