Mental Strategy

Breaking bad habits is like performing a mental trick on yourself! I pray earnestly about my problem but it keeps re-emerging at times. I have to fight it almost every single day and it is like I am warring against my very soul, fighting for freedom on a mental battlefield of sorts. The enemy knows my every weakness and my every strength. I wonder if I will ever be victorious? It's like if I come up with a strategy the enemy is right there hearing my every plan and it almost makes no sense to even try. By God's grace I will never give up!
