80%-90% in the first 10 years of experience, less than 10% within the recent 5 years. Both personal and professional projects. Once you go live, it's far easier to release new things. You can spend 2 years working on things that never come out. There, 100% of your time is spent working on things that fail to launch. But after the launch, that 100% is converted to 0% for the whole two years. You work on something else for the week, and then that goes live the next week too. Also the team has to hold together long enough for launches too. No layoffs, salaries good enough, tech debt low enough. This seems to happen more further up the career ladder.
