Often times we run into the need to make a tough decision.
One way to help is to use the 10/10/10 rule. Imagine how you would feel about the decision, 10 minutes from now. Then imagine the feeling 10 months from now. Finally imagine how you would feel 10 years from now.
Imagine you have been dating someone for a while. Things are going good, but you feel it’s time to take the relationship to the next level. You want to say “I love you” but are not sure if you should. To help you decide, imagine that you have already said the phrase and 10 minutes have passed. At this point you will have either found out if they said “I love you” back, or you would have gotten another response. 10 months from now, you are either in a happy relationship, or have found someone new. 10 years from now, if things go well you are still with the person you are currently dating, or you would have completely forgotten that the conversation had even happened. The result, saying it has little downside. You are either going to push the relationship forwards, or you will have forgotten the results of the action eventually.
There are tonnes of ways to help your decision, this technique and many of the others can be found in the book Decisive by Chip and Dan Heath.
