You can accomplish most things worth accomplishing without extreme effort. In fact, giving things your all might be counterproductive.
You get tired and make mistakes. You have unreasonable expectations and feel bad for falling short. You spend most of your time on one project and your other responsibilities and goals suffer.
Of course 110% effort isn’t possible. Neither is 100%. Even 90% is too much. Instead, some experts suggest you dial down your effort to 85%.
Supposedly, that’s the sweet spot. Enough effort (time, energy, commitment) to be manageable and avoid burnout. Enough to allow you to do your best work and accomplish your most important goals.
You’ve only got so much juice to give. Scale back. You’ll be more productive.
