I’m new to fiverr and this is my first gig, but I think I have the capability to create a valuable, high quality post for anyone. So I hope you can let me help you. I will write an article in which you can do whatever you want with it. You can post it on medium, facebook, or even have me post it on my blog and have it sponsored by you with links back to your social media, etc.
I own a blog where I write about exactly the same things. Topics included are: meditation, self actualization, mindfulness, happiness, motivation, self improvement, depression, ego, sports, etc. Almost anything you can think of in the personal development niche.
