Grasp all, Lose all paragraph for any class

Imagine you have a bunch of things in front of you, and you want to pick them all up. If you try to grab everything at once, you'll probably fail because your hands can't hold everything together. They will fall off, and you'll lose everything. However, if you pick up each thing one by one and hold them securely, you'll be able to collect everything without any problem. So, instead of risking losing everything by trying to grab everything together, it's better to pick up only a few things each time that you can hold in your hands. 

This idea is like a lesson from experience. Success usually happens step by step, not all at once. If you try to do everything at the same time, you won't achieve your goal. In the end, you'll feel disappointed and sad. It's better to focus on one thing at a time and make progress little by little. That way, you'll have a better chance of reaching your goal without feeling frustrated or unhappy.
