Aim for 100% effort even if you only hit 80%. You'll still outperform your comfort zone baseline of 50%. Growth requires pushing past what feels safe, even when you might fall short.
I feel like what you just explained is that, like, just picture a bubble. So when you're within your bubble, you can meet all the deadlines, you can do all the things in a very comfortable, timely manner. But in order to grow, you have to expand from that. And sometimes you can put too much on your plate, but at least you're shooting for 100%. And if you fall short, then maybe you fall to 80%, but that's still higher than 50% if you started in that comfort zone. Does that make sense?
