that simply starting on interesting research problems and committing to them is the way to go. And don’t start a new paper until you finish/publish an old one. At least once you hit the steady state of 4-6 projects in various stages at any time.
No new papers until an old one is done. So there is a double celebration when one is accepted—the old one is of the desk, and you can start something new.
And just starting working on an issue is enough. No one that I know of can successfully see to the end of the project when they start if. If they can, the project is too unambitious.
