Slow lessons

I am learning something valuable along with my toddler. She is 3 years old and has just started speech therapy. Her language use and comprehension is great, but her articulation needs a lot of work. You see, she has a lot of wrong pronunciation habits developed over the last few years. The thing is, I really expected to see major improvement after each session. Her speech pathologist says she is doing great and that her progress is, and should continue to be, quick. I am, however, not so sure. I guess I wanted to see instant fixes. Every time I work with her on the assignments for the week, I feel frustrated that we are still working on the same things. But it has only been a few weeks!
It hit me how much this is an illustration of a great difficulty I have. I want instant fixes for everything. Quick answers, swift decisions, 180 degree turns on a dime. But there are bad habits I have spent a lifetime developing (and unlike my toddler, my lifetime has spanned more than a few years) so how can I expect instant change in the other direction? Does that mean I give up and stop working with the Holy Spirit on these horrible flaws? Of course not, but it does mean I need to develop my patience and trust that God's timing is perfect and He will complete the work in me one step at a time. So, I will continue to persevere and run with endurance, even when I don't feel like it, because He asks me to, because He knows best, because He loves me enough to take my own sins onto His sinless body and die a death of atonement for my salvation.
