Blaming Time?
If I catch myself saying, "I dont have time for this," that basically means, "it is not high up on my priority list".
Don't blame the unavailability of time.
It is basic manners to ensure that I focus on my mistake rather than the mistake of others: I can't fix that, I can only try to fix myself.
Sure, time is always running short. But if my priorities are set, it shouldn't be a problem. So yes, if you are not praying as often as you want to, if you are not working as hard as you want to, if you are not doing [insert awesome behavior] than it is wise to focus only on your own lack of priorities in life.
