Patience

When building something you have two options:

1. Understand and accept the trade-off between good, fast and cheap;
2. Be impatient.

I appreciate the first option isn’t very popular at the moment. It’s almost old fashioned.

But I also know that everybody I know who has built something worthwhile has ignored all of that and focussed on quality and efficiency, and on sustaining themselves through the longer-than-you-think that it actually takes.
