Being a practicing Muslim means you have to fulfill your obligations. Pray your prayers on time, try to contemplate about God every once in a while, remember the afterlife. If you do this, you will always have God in your heart despite the many distractions. As for halal wealth, you should know that having less wealth and it is halal is better than having more wealth which is haraam. At the end of the day, God will not leave you hungry. He created you and He will send you your sustenance.
