Do you track your time? How many hours do you spend on your projects?

Hey Indie Hackers!

Are you currently tracking your time, when you are working on any projects? If you do so: How many hours do you spend on your projects per week?

For me, it's approximately 10-14h/week. Thats only for my sideprojects, while I spent most if my days working full-time as a consultant. But I didn't track my time working on sideprojects exatcly in the past. Now I want to start doing so!

What experiences have you made with time tracking? Any advice on tools and techniques?
