Scientists have found that willpower is like a muscle. The good news is that you can actually train your willpower and make it become stronger.

That’s why surfing the internet or Facebook becomes even more “irresistible” at the end of a long day, food choices get worse as our willpower muscle weakens and it even explains why dieters are more likely to cheat on their partners.
