Billionaire investor Chris Sacca, whose investments include Twitter, Kickstarter, and Instagram among others, was recently on Tim Ferriss' podcast, The Tim Ferriss Show.
He brought up a good point about why he openly shares his investing strategies and secrets. It really underscored why I share as much as I have about freelance work and filmmaking here on my blog, culminating in my 11,000-word essay on Medium, The Little Freelance Handbook.
You can listen to the podcast here, but to paraphrase Chris' reasoning:
Sharing secrets or strategies only takes you so far. It requires execution to actually have success with those tips. If you don't have the passion, or frankly, the skill to compete, then it doesn't matter how much I share. But if you do, and the advice given helps you even just a little bit, you'll be an ally for life.
