Who says that your goals have to be year-long? Have you thought about having month-long goals?
Often the reason we fail when it comes to our long-range goals is because they are too big. The way to correct that problem is to make the goal smaller. If the goal is smaller it is more manageable and easier to complete, making you more likely to succeed and go on to the next goal.
If your goal is to get your family to read the bible every night together, then perhaps reading a chapter in the book of Proverbs everyday would be a good starting point. The accountability is there since there are 31 chapters and the book of Proverbs is a wealth of information when it comes to the pressures of life. Once the habit of sitting down and reading together is established, more can be added.
If your goal is for your family to be healthier in the New Year, start one day at a time. Decide how you are going to address getting healthy in your eating habits and take one step at a time. Then also introduce exercise. Family walks in the evening after dinner is great bonding time.
By having monthly goals they are more attainable, but there is an additional advantage of the family staying on the same page throughout the year and staying focused.
I can do all things through Christ who strengthens me.
