Li-rfuas Chaim Yonatan Mordechai ben Pesha Elka
There are 48 ways to acquire Torah and according to the Sfas Emes, every day of the Omer we should be working on one of them [and review all of them on the last day] and then we are ready to receive the Torah on Shavuos.
Today's kinyan Torah  is שמח בחלקו - being happy with what you have. How does being happy with what you have enable you to acquire Torah??
One answer: People who learn often lack for their material needs. If one is not happy with what he has then it can really shter [impede] one's learning.
So if you are learning and feel that you don't have what you need - switch the "cd" in your brain. You have EXACTLY what you need.
Now you are one step closer to acquiring Torah.....
