Keep your hobby secret

· · ·

A founder builds something real — customers paying, product working. But they don’t feel successful until a VC writes a check. The check becomes the diploma, the permission to believe in themselves.

This is backwards. A VC saying yes means your startup fits their thesis. A VC saying no means it doesn’t. Neither tells you whether your company is good.

The same trap exists everywhere. A friend picks up painting, posts it on Instagram, and within a month they’re painting what gets likes, not what they feel. The moment you seek external validation, you lose ownership of the thing.

Here’s a filter I believe deeply: if you have a hobby and feel zero urge to post it — protect it with your life. That impulse to keep it private means you’re doing it for the purest reason possible. Because it feeds you.

The moment you share it for applause, the audience becomes your client. The thing that recharged you becomes another job.

Not everything needs an audience. The most valuable things in your life are probably the ones nobody knows about.
