On protection You don't wake up every morning fully protected from all afflictions, whether they be physical or mental. You have to prepare yourself every day for the various forms of resistance that you will face, or else you will fall to them and fail to live your life to the fullest. Have you not seen yourself fall so easily to distraction for hours on end, which all started with the tiniest lapses of attention? Have you not experienced a small misjudgment turn into a large blunder? In these moments you had not properly protected yourself. Rather, you woke up and decided upon nothing. You made no active decisions to do great work or be focused on a goal. You acted according to the desires and diversions of your own body. And what has this body done for you to earn the respect of your will? Your will must overpower your propensity to be indulgent and slothful. Indulging in your sleep or your rest is only pleasing until the day comes demanding it's share of your life. When your own guilt at having done nothing overcomes you, how can you at that point call yourself free? Protect yourself at all times from these attacks on your freedom.
On peace Recognize what brings you solace and bring more of that into your life. I've seen that your ability to develop relationships, mentor, and learn from others is much greater when you are not in a group but one-on-one. This is, in essence, your medium. Instead of pushing yourself into another medium and attempt to make peace there, stick to where you know you are strong and become better. You are far less peaceful (though not a disturbance to others, by any means) when you have to be a part of large groups, and that's okay. Make more efforts to put yourself in the situations in which you can love others the most effectively. This will bring you peace rather than perturbation.
On struggle Remind yourself that the obstacle is the way. The fact that you don't want to write at this moment means that you should be writing. The fact that your mind calls on you to give up because your idea is a failure is the number one signal for you to power through and change it until it becomes better—even if it means giving up on your original idea to pursue another. For what great creation has emerged without a struggle? What great man or woman had no obstacle to overcome? Instead of saying that you "have to" overcome the struggles of creativity, remind yourself that you "get to." Few have this privilege. Don't take that lightly.
