Indecision is your enemy. It can stop you in your tracks. It may cause you to put all kinds of effort into comparing your options. What are the pros and cons? What do other people say about it? What if they're wrong? You can analyze it to the millionth degree. And you still end up stuck.
I recently went through a bout of indecision and learned some things. Perhaps they won't help you but they helped me.
So what should you do if you can't decide?
First you have to realize that there is another choice: do nothing. That is what gets decided when you can't make another decision. Is that the best decision? Sure maybe it sounds like you're being indecisive again but let me give an example. One of your children breaks a rule. There needs to be an appropriate response - it may not always be a punishment, depending on the circumstances - but it needs to be something. Out of all your options, however, doing nothing is almost never appropriate. Realize that by not choosing, you're actually choosing. It should help motivate you to make a choice and be done with it. Will it always be the best choice? No. Is it possible you'll regret it later? Yes. However, it is far more probable that you will regret doing nothing than you will regret making the wrong (or less right) choice.
In the end, you must simply give yourself a deadline. By this deadline, you will either choose one of your options or none of your options, but you will make a choice and go on with life.
That's my advice. Don't let indecision eat you up. You will be much happier.
