1. Why would you wait until the end of the year to make the effort to attempt to change something in your life?
Not to be rude, but you have all year to make changes!
2. When you think about it, you make resolutions for yourself all the time.
In the middle of the day, you could be thinking, "You know, I haven't read a book in a while. Let me challenge myself by reading one book. If I get through one book, then let me try to read two more."
3. Resolutions are short-lived.
It's possible that you might forget about your resolution a week or two after you made it.
4. Life is not linear in terms of time.
Don't wait for the end of a year to try to make changes. Anything could happen.
