“Satisfaction, for us, is only a brief thing. The man who acquires wealth does not reach a point where he has enough. Success for us is more like acceleration than speed. Interest cannot be maintained at a constant level.”
– Neal Asher, The Skinner
You should always celebrate when you have succeeded in delivering a project, presentation, or when you helped someone in a good way. And then you should ask yourself:
What did I learn from this and what will I do different next time?
It is a fine balance between getting annoyed with yourself for all the errors you did and learning so you can do better next time. But it is a balance you should practice every day so you can keep on accelerating.
