Do you track your goals, mood and habits?

Hello! I've always been really interested in self-improvement in my daily life. A big part of that is building and maintaining positive habits. I've tried tons of different apps, tools, and techniques to keep track of my progress, with varying amounts of success.

As a software developer I want to create a productivity management system/habit tracker that is better than what is out there. Something that is simple, flexible, and effective. But I only have my own experiences to rely on. I need to hear from other people who track their habits, successfully or not. What works, what doesn't, what frustrates you about the apps or tools you've tried.....

I've created a survey to capture people's thoughts about this topic. Here is the forms: https://forms.gle/Wcybx6uF9w3mbHaL6

Thank you so much!
