....Is the one that you actually do.
It's simple, but not easy. You don't have to have every detail planned out weeks ahead. That is stressful and time consuming. Plus if you happen to fail on one of those details then you're going to be let down and not have much motivation to continue.
Instead, just figure out a plan that you will actually stick to and then see it through to completion. It might not be the greatest thing ever but it will be a learning experience. You'll know exactly what to adjust the next time around.
