The more we fall in love with God the more we want to get rid of all sin in our lives, especially the habitual sins. That doesn't say we will never sin again, but sin will not be rooted. Sin is an act of non-love. Love is the opposite of sin. We must never get discouraged. The Saints tell us that it takes a life-time to become freer of sin in our life. But by constantly uprooting and not allowing sin to have a sway in our life, then we will desire God more. Love is the antidote of sin. The journey to God has many pitfalls, but it also has many graces to avoid the pitfalls.
