On sentences As you know, our correspondences will soon be coming to an end. I've committed to writing to you for ninety days, and we are only a handful away from that being over. Perhaps you will still want me to correspond with you, though I can't guarantee that it will happen. However, I do want to recommend a writing practice of your own: compose one sentence that summarizes a feeling or significant event in your life. It's a compelling thought experiment on a daily basis. For one, you have to make a decision on the one theme or happening you will address with your small amount of ammunition. In addition, you can't explain much, so you might have to employ other means. Maybe that's an analogy or a variation on a saying, but no matter what, you have to get creative. It's also a fun way to exercise your simplifying muscle. You can't talk in detail, so you find out what's truly important rather than wasting your words (like I do) on the rest of it.
On patience Frustration is not a driving factor in your ability to do great work, and neither is impatience. The distinction has to be made between a childish inability to wait and a desire to push to completion. If you want results now and are focused on outcomes, you'll become frustrated when they don't come as quick as you want them to. On the other hand, if you are clear about the work you need to do and are eager to get it done, that's a different story. You shouldn't become frustrated but only more ready to bear down and labor away. In creative endeavors, it's all the more important to be patient but diligent. You won't create the perfect solution to every problem you encounter within the first sixty seconds of contemplating it. If you become frustrated, you'll only distract yourself from creativity itself and you'll make no progress. I should also address your recent problems with your own abilities. Those are due in large part to you being impatient. Though I'm not saying you should delay your efforts until you have more knowledge or study—in fact, delaying for that reason would make you as slow as the students who choose to go to college without first studying on their own. However, you don't have to be at peak condition now. You don't have to be in your prime 24/7. I wish you a great and steady career and life, but you will have a rise, a fall, and hopefully, another rise. You will learn, fail, succeed, and everything in between. You're in the learning phase and that's okay. Embrace it and do your best learning possible to prepare yourself for a future of success.
