To be efficient you need to find the right balance between work and life. Too little work, you are lazy, too much work, the quality of your work drops to the point you could work very little (as time) and have the same result. Also this balance needs to be adjusted daily. You can't work, work, work and then recover by going in a holiday. It's similar to gas/air mixture in engines. You need to have it right all the time. You can't inject only gas in the engine and add the air a week later. What this means for me is that I take time for breakfast and lunch. I leave at 5 pm all the time. I stop working when I'm too tired (quality will be crap and I will need to fix it later anyway). Going out in nature and whatever makes you feel that you are relaxing. Daily.
