Who can demonstrate willpower and who cannot?

Previously, it was believed that every person is capable of developing willpower, but most simply do not want to make an effort, they are lazy, undisciplined, etc. However, recent scientific findings show that this is not the case. If you have inherited genes determining the malfunction of neurotransmitters, they will always function that way. Your brain will always struggle to control momentary emotional impulses, making you more prone to impulsive behavior. So, no matter how many articles you read or engage in specific self-training exercises in front of the mirror, your genes will not change, and a new brain will not grow.
