A common type of unrealistic expectation is perfectionism. It is expecting that you will be perfect at every step of the way, that you will perform flawlessly, that you will never skip a day or make mistakes. When you think like that, you will treat many of your results as failure, engage in “not good enough” thinking, and fall into the pit of self-criticism and shame.

Being excessively hard on yourself is not conducive to Mindful Self-Discipline. And it’s not healthy either. As a remedy, accept that you will mess up from time to time. Accept that perfection may be a noble thing to aim at, but it will never be something that you actually achieve. Remember, Mindful Self-Discipline is built on the foundation of awareness, and it is the nature of awareness to see and accept things as they are. 

If you are the type of person who beats yourself up whenever you fail, then naturally you will fear failure—which leads to procrastinating and perfectionism. On the other hand, if you habitually practice self-compassion, then you know that if you fail you will still be okay; this leads to taking more steps in your life. It leads to courage.

Know that you are not alone. Know that other people have gone through similar challenges and felt the same way. Be kind to yourself. This is a process, and you will never be perfect. That is okay.e.
