As for execution, though... Trust your training.
I crushed my training. I trained smart. Races are won in training. And I won that race against myself.
I was consistent. I prevented injury. I kept perspective.
Consistency
After Marvin gifted me my Garmin watch, I became a "consistent" runner for the first time in my life. The GPS watch and the Strava app motivated me to log my training and rack up the necessary miles for aerobic improvement. Before that, I ran maybe twice a week and sometimes went for weeks at a time without running. I also battled injuries more often because I was such and on and off runner.
However, once I learned that I didn't have to run everything at 7:30-8:30 pace and that easy efforts were more important than hitting acceptable paces, I became a better, more consistent runner. I accepted my lack of aerobic endurance and relished in the ideas of "base building" and low heart training. I now think a big aerobic base is the most important part of a runner's training arsenal...
Motivation was also important. In addition to running easy, the 128 day run streak struck me on the days where I just didn't want to get out. Once I got to 50, I said.. I have to get to at least 75... and then I couldn't just stop there, I had to get to 100.. and so on... I conquered bad weather (thunderstorms and the rainiest season California has seen in decades), travel (I once ran in circles in an airport terminal during a layover), and general laziness (need I explain?). Making the goal to run every day kept my training momentum going. In future marathon training cycles, I may do another run streak or define a similar goal (like 6 days a week for x weeks).
Injury Prevention
You can't be consistent unless you avoid injury. Slow running was critical for this. In my mind, I had to build up my tendons, ligaments, and bone density to handle the stress of long distance running.This is something I feel like a lot of people miss when they talk about training for a marathon. When people think about training for a marathon, they think about training their cardio. Can they last xx:xx pace for 3-5 hours? But there's so much more to it than that. It's about training all aspects of your physical endurance: bones, ligaments, muscles, heart, lungs... Even more important, it's about training your mental endurance and mental fight in the last push towards the end. This is why marathon training is all about the recovery.. getting enough sleep every night, foam rolling, tiger balming, dynamic stretching, strength training, and even some yoga -- all things I incorporated on a regular basis.
Perspective
One thing about marathon training has been that life goes on around it. From my human physiology and python programming courses to the stresses of work to taking care of my pup to nurturing my relationships, running has been a part of my life that, well, honestly, can't live with it / can't live without it. That's true for any other physical training endeavor I might take on.
As obsessed as I was with numbers and training, I also had to make sure recovery was my number one priority. There were a handful of weeks where I had to reduce my training load or change up my training plan because of exams or stressful work weeks.
Then there was the rib injury 3.5 weeks out from marathon day. I had to cut out my final long workout (planned 22) because my bruised ribs were making it hard to breathe. And my mileage reduced dramatically earlier than planned. I have to hope first and foremost that the rib pain is negligible by marathon time. Second, I have to accept that the last "hard" week of training had to be sacrificed for the sake of recovery. Taper might have started early but I still have a lot of fitness from the six months leading up to the marathon. And that counts for something! The only thing left now is to enjoy the taper. :)
As for time goals - I don't need to run fast for my first marathon. I have nothing to prove except that I have now built up a solid aerobic base and I am a better runner from the training process.
