Word-of-Mouth Marketing works_it really works
But process is slow_like turtles
It took complete 1 year to make WOM sucessful to make my name as a pro. content writer and social media strategist.
I let clients to approach me based on WOM.
But reccomendation is The Key. I sow my best of my self for them, they pour water of reccomendations  and at last I cultivated more experiences and knowledge.
