This is how to have more energy:

• Meaning: Do things that benefit others. Effective “job crafting” starts by looking at how much time you dedicate to specific tasks that give you energy each day. When university call center employees who were asking alums for donations got to meet the scholarship students who benefited from their work, productivity, enthusiasm and the amount of money coming in went up dramatically.
• Interaction: Be 80% positive. (I am 99% certain of this.) People consistently said that the most positive times in their lives all had to do with belonging and connecting -- not achieving. When researchers ask people to reconstruct the most positive and negative experiences of their lives, they consistently describe social events as their most influential memories over a lifetime. “In short, it was the moments of connecting to others that touched people’s lives the most.” 

  My team’s research found that people who reported having great interactions throughout the day were nearly four times as likely to have very high well-being.

  
  How can you guarantee that? Make close pals at work. But how do you know if you're really friends with someone at the office?
  
  Ask yourself how much you share your personal problems with each other.
  The telltale sign of a friendship between co-workers was the amount of time they spent talking about topics unrelated to work. Then the next phase, a very close friendship at work, was marked by something less intuitive: sharing problems from one another’s personal and work lives.
• Health: Eat better, move more, sleep long and well. A 2014 study suggests that highly processed foods with added sugar may also contribute to laziness. Even “comfort foods” like baked goods actually have the opposite effect of comfort and are likely to make people more depressed. When people exercised moderately for 20 minutes they felt better... for up to 12 hours. So get to the gym early and you can boost your mood for almost the entire day.
  

  When researchers assigned one group of participants in a study to do 20 minutes of a moderate-intensity workout, they found that the participants had a much better mood immediately following the exercise than a control group who did not exercise. What surprised researchers was how long this increase in mood lasted. Those who exercised continued to feel better throughout the day. Even two, four, eight, and twelve hours later, they were in a better mood than the control group.

  While many concentrated on his findings relevant to 10,000 hours of deliberate practice, the other factor that differentiated top performance was sleep.
