3 keystone habits that'll change your life this year

Exercising regularly is perhaps the most impactful keystone habit you can implement.

When you take up exercising on a regular basis, you start eating healthy. And you start feeling good about your body. You procrastinate less and you get good sleep.

When you get adequate sleep, your mind and body are primed for a productive day. 

That means more energy and mental capacity to do the work you want to do — and do it well.

• Early morning hours are prime for productivity: early risers tend to have a higher level of cognition and the ability to solve complex problems.
• The morning is the time when your willpower is at an all-time high: when we wake up, our willpower is still high because we’ve used less of it. As the day goes on, our willpower is depleted.
