Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way. The real test is not whether you avoid this failure, because you won't. it's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.
Wait with patience and love and strength. If helpers are not ready now, they will come in time. Why should we be in a hurry? The real working force of all great work is in its almost unperceived beginnings.
Your good mother tells me you are feeling very badly in your new situation. Allow me to assure you it is a perfect certainty that you will, very soon, feel better - quite happy - if you only stick to the resolution you have taken to procure a military education.... On the contrary, if you falter, and give up, you will lose the power of keeping any resolution, and will regret it all your life.
A principle is a principle and in no case can it be watered down because of our incapacity to live it in practice. We have to strive to achieve it, and the striving should be conscious, deliberate and hard.
