Discussion
Cooking most meals from scratch with whole, fresh ingredients, growing my own vegetables and herbs in the garden, generating electricity with solar panels to reduce reliance on the grid, managing my finances carefully through budgeting and saving, keeping my body and mind healthy with regular exercise and mindfulness practices, securing my Bitcoin with self-custody and holding my own private keys, running a Bitcoin node to stay connected to and support the network, fixing and maintaining things myself with DIY skills, reducing waste through composting and living sustainably, and always learning new skills to stay independent and self-reliant such as language learning.
