What is the best way of self-reformation?

Answer

The only way of reforming oneself is to submit to the Shariah and adopt the Sunnah way of life. There is no other way. Improve your knowledge of Islam by reading reliable Islamic literature and implement the teachings of the Deen with diligence. Read the life episodes, advices and admonition of the Auliya. Insha-Allah, you will then achieve moral reformation.
