It takes time to create strong foundations. Failing to allow patience into a process develops guilt and frustration because we have unreasonable expectations of results. Thinking that you are going to paint a masterpiece the first time you start to paint is wildly unrealistic and unhealthy for your process of learning this new skill. It would take many years of hard work on top of what natural talent may exist to become a proficient and respected artist.
It can also be a cop out if we say, "That is too hard! I could never be that good." Not being graceful and patient, giving yourself permission to face the process, always leads to certain failure.
Where do you find you have perfectionist tendencies or visions that keep you from being patient with yourself?
Prayer: Pray that God would show you areas where you have unrealistic expectations, esspecially those that you might not know about.
