Building something timeless requires giving up so much of your own precious time that you’ll only have the opportunity to build a limited number of timeless masterpieces in your life.

Choose wisely. It will always take longer than you think, no matter how smart you are. The way appears as you walk, the bugs emerge as you run, the plan evolves and crystallizes only after many failures.

Succeeding won’t give you eternal happiness. But if you build something you love, you can enjoy it when you use it everyday.
