The Power of Fast

I have one constraint that I constently fight. Time. I never have enough. And, I get bummed when I have to wait. Airtight does a great job of illustrating this point.

So my main piece of advice, from a lifetime of using and building computer apps is - make it faster.

Make it smaller
Make it lighter
Sacrifice unnecessary functionality
Preload when possible

Give the user instance response. If you can’t do that, then at least give them instant feedback with some kind of front-end animation, and try to accurately indicate how long the user will be waiting.
