Ask HN: How do you build a close support network to help achieve your goals?

At YC, groups meet every other week to discuss company goals and progress, learn from each other's experiences, and get guidance from their mentors. This system helps founders realize and adjust their goals and plans for what comes next, and helps enforce those goals by adding some amount of accountability.

Have you used a similar system for your personal life or career?

Do you have any experience forming small groups of friends or colleagues to regularly discuss goals?

What systems/tools do you use to help you achieve your goals?
