Self-control is something you struggle with often. You tend to borrow from your future instead of preparing for it. The attitude that you will fix things later rather than solve problems now can lead you to over-indulgence, overspending, and ignoring some of the more important details of daily life. Procrastination may be a shortcoming. You may choose to take the easiest way towards achieving your goals. With maturity, you learn that a lack of self-control inhibits your progress in life, and that moderation is something that you should strive for, although it should be noted that this is not an easy thing for you to master. It requires dedication and periodic checks to control your impulses towards immoderate behavior.
