So you need to either commit to making an important project go somewhere by promoting it constantly.
Or you need to use it as a reason to make more work. If a hypothetical 10% of your work goes somewhere, then making 10 projects mean one goes somewhere. But if you make 100 projects, then you can expect 10 to go somewhere.
A lack of progress can either be a reason to double down, or to take a break and start the next project. It’s not a reason to quit trying.
