For me the Qur'an isn't just teaching me about Allah and how to be a better person; it is also teaching me about myself. Who I am and how I should be. All the things that I thought I needed, I know now that I don't. All the things that I craved and wanted, I no longer need. Although it will take me a little while to put things right and get on the 'straight path'. In'sha'Allah I am going to get there.
If you want your life to improve the first step you need to take is to really look at yourself, and then make the changes that are needed to improve your life.
