“Experiment: To replace negative character labels, try the following steps:

1. Pick a new, positive character label that you would prefer. For example, if your old belief is “I’m incompetent,” you would likely pick “I’m competent.”

2. Rate how much you currently believe the old negative character label on a scale of 0 (= I don’t believe it at all) to 100 (= I believe it completely). Do the same for the new positive belief. For example, you might say you believe “I’m incompetent” at level 95 and believe “I’m competent” at level 10 (the numbers don’t need to add up to 100).

3. Create a Positive Data Log and a Historical Data Log. Strengthening your new, positive character label is often a more helpful approach than attempting to hack away at the old, negative one. I’m going to give you two experiments that will help you do this.

Positive Data Log. For two weeks, commit to writing down evidence that supports your new, positive character belief. For example, if you are trying to boost your belief in the thought “I’m competent” and you show up to an appointment on time, you can write that down as evidence.

Don’t fall into the cognitive trap of discounting some of the evidence. For example, if you make a mistake and then sort it out, it’s evidence of competence, not incompetence, so you could put that in your Positive Data Log.

Historical Data Log. This log looks back at periods of your life and finds evidence from those time periods that supports your positive character belief. This experiment helps people believe that the positive character quality represents part of their enduring nature. To do this experiment, split your life into whatever size chunks you want to split it into, such as four- to six-year periods. If you’re only in your 20s, then you might choose three- or four-year periods.

To continue the prior example, if you’re working on the belief “I’m competent,” then evidence from childhood might be things like learning to walk, talk, or make friends. You figured these things out. From your teen years, your evidence of general competency at life might be getting your driver’s license (yes, on the third try still counts). Evidence from your early college years could be things like successfully choosing a major and passing your courses. Evidence for after you finished your formal education might be related to finding work to support yourself and finding housing. You should include evidence in the social domain, like finding someone you wanted to date or figuring out how to break up with someone when you realized that relationship wasn’t the right fit for you. The general idea is to prove to yourself that “I’m competent” is more true than “I’m incompetent.”

Other positive character beliefs you might try to strengthen could be things like “I’m strong” (not weak), “I’m worthy of love” (not unlovable), and “I’m worthy of respect” (not worthless). Sometimes the flipside of a negative character belief is obvious, as in the case of strong/weak, but sometimes there are a couple of possible options that could be considered opposites; in this case, you can choose.

4. Rerate how much you believe the negative and positive character labels. There should have been a little bit of change as a result of doing the data logs. For example, you might bow believe “I’m incompetent” at only 50 instead of 95, and believe “I’m competent” at 60 instead of 10. You’ve probably had your negative character belief for a long time, so changing it isn’t like making a pack of instant noodles.”
