Christians fail at time management for many of the same reasons those who aren't Christians fail at time management. However, Christians also fail because they feel like some of the good secular information on time management doesn't apply to them because it isn't 'Christian' in nature. Without further adieu, the top 5 reasons Christians fail at time management:
1) Christians fail at time management because they are not willing to apply time-tested techniques of time management to their own lives, thinking that the current information on time management must apply only to those who are not Christian. Unfortunately, this close-minded approach to self-improvement, although successfully protective against the outside world, can prohibit true growth.
2) Christians fail at time management because they unwittingly think that if they simply put their beliefs first, they will win at everything they do. Although this may be accurate in principle, Christians must recognize that the same laws of success and productivity that operate in this world, work for them also. This is certainly not to say that a Christian should ever sacrifice his/her beliefs for productivity, just that productivity principles can work for both Christians and non-Christians alike.
3) Christians fail at time management because they are often unwilling to put serious effort into a self-improvement project that does not have decidely Christian undertones to it. Again, Christians should recognize that the Bible calls them to self-improvement and self-control, and Christians should make every effort to improve both their productivity and their time management skill set.
4) Christians fail at time management because they sometimes have difficulty prioritizing what needs to be done. We all, Christians included, need to create a set of goals and create priorities that help us get to our goals. Without goals and priorities, most people, including Christians, cannot function at their most productive level.
5) Christians fail at time management because they are often unwilling to commit to long-term self-improvement, thinking that their relationship with Christ will simply make them a better person, without any additional work. Although a relationship with Christ is critical and can improve an individual's behavior, the Bible is very clear that we have to make an intentional effort at controlling ourselves and becoming productive.
With all of this in mind, I conclude that Christians and non-Christians alike should make a continual effort at self-improvement, including time management mastery.
