The first major revelation for me was answering the second question: “where did it come from?” If you break down any given negative emotion, the answer to that question is always the same at the root: me. An external event may have triggered it, but it’s always me that generates a reaction, whether negative or positive.

But, maybe they’re lazy and just intentionally doing half-assed work. Even so, anger won’t help. Let’s find out why. Again, an honest, anger-free conversation will more effectively lead to a solution than letting the rage pour out. Even when the answer to all of these questions is unacceptable — they just did bad work — problems can be solved without letting them hurt us. Fire someone compassionately with a clear head and move on.

Improve your squat and deadlift with this simple drill you can do at home. Here's how.

1. Stand facing a wall with your nose and toes against it. Your feet should be slightly wider than shoulder width with your feet angled out very slightly.
2. Squat down as far as possible with your arms hanging between your legs. (I prefer this to the variation where the arms are kept high.) With each rep, you should be able to drop a little farther.
3. Perform 3 sets of 15 reps every day until you can drop your hips below your knees.

The dirty little secret about JS frameworks, not just Ember, is their abysmal performance on mobile devices. First, we have to download the huge runtime on a slow connection. Then, we have massive amounts of framework code running on a device which has a slower processor to start with, but may also have an inferior JS engine. The result can be latencies in seconds or even tens of seconds merely to display a page. There is no simple solution to this problem.
