A good house is one you have contributed to build or improve.
A good version control system has a good UX and you are done learning it in your first day. Git is far behind.
A good static site generator should not force you to read hundred documentation page beyond HTML/CSS.
A good service or platform or social media is one you do not fear to lose access to.
A good blogging platform is not one for which you pay thousands dollars for a CSS transition effect.
A good game engine is one you understand very well and can optimize to your needs.
A good CI or build script is the one you own and maintain.
An awesome meal is one you cook.
A perfect blog post is one you write without help, without filter, without caring about comments.
Everything you will build yourself is awesome, because it is unique and not forced by anyone.
I wish you an imperfect but awesome new year!
