Best of Neil Patel

Thoughts on Sigma Digest

So much better than my RSS reader. I don't have to spend time searching for drops of valuable articles in ocean of boring & repetitious trash anymore.

Sigma Digest saved me 7 hours every week, which I can now spend reading those articles. Really superb return on investment.
