A: Taking care of small things makes great things come from Lenin.

We must pay attention to small things before we do big things, because every big thing is paved with many small things, so we can't achieve big things if we can't finish small things. The same is true for being a man and doing things. People who achieve big things generally succeed from the bottom up, and there is no natural genius, so they are small things and have achieved big things. ? Drops of water see the sun, and small things see the spirit. Without the accumulation of small things, how can we achieve great things? "If you don't accumulate a thousand miles, you can't become a river without accumulating a small stream." Everything is accumulated from small things, and from quantitative change to qualitative change, it is a process of accumulation.
