From this passage, what difficulties did the author encounter in the process of learning? How did he overcome it?

1, the family is poor and can't afford to buy books.

When the weather is very cold, the water in the inkstone pool is frozen into hard ice, and fingers can't bend and stretch.

3, when looking for a teacher, carrying a book box and dragging shoes, walking in the ravine, the winter wind is very cold, the snow is several feet deep, and the feet and skin are frozen and cracked.

4, eat two meals a day, have no fresh, fat and delicious enjoyment, and wear shabby robes.

Overcome:

1, I can't buy books to read, so I often borrow them from book collectors and copy them myself.

2. Overcome it optimistically.
