1. First of all, how do you measure your perfectionism and subjective well-being? With a questionnaire?

2. Make sure that there is no intermediate variable between your personality traits, perfectionism tendency and subjective well-being.

3. We can use the correlation coefficient between personality traits, perfectionism scores and subjective well-being.

4. It can also be judged by whether there are significant differences in subjective well-being between the subjects with high scores in personality traits and perfectionism and those with low scores.

Finally, I suggest that you should think of statistical analysis methods when writing research and design before making a paper in the future.
