The crucial aspect of changing anything about yourself or others is having a strong enough reason why to change. You'll find that the more reasons you gave to create change the more likely it us to happen
One of the most powerful stories about the power of why came from Victor Frankl who was a successful psychiatrist in Austria in the 1930’s. His wife, parents and children we arrested and imprisoned in a Nazi concentration camp in 1939. He watched as his children and parents died in the camp, and he saw his wife taken to Belsen concentration camp where she later died.
Frankl noticed that some of his fellow prisoners died during relatively easy challenges, while others refused to perish even in extreme conditions. He found that those who had a strong enough reason why to live and endure the hardship found a way to survive, while those with less compelling reasons found it harder to survive. He wrote that:
"Ultimately, man should not ask what the meaning of his life is, but rather he must recognize that it is he who is asked. Each man is questioned by life and can only answer to life by answering for his own life, by being responsible. Responsibleness is the essence of human existence."
