Answer:
The meaniing of: In seeking great happiness small pleasures may be lost. Is:
That a person that wants a high level of happiness will be driven by it, leaving smaller happy moments, or joys behind.
Step-by-step explanation:
This proverb bases its analysis in two statements, the first one is that if you look for a great level of happiness you are going to be driven to it leaving small joys or good things behind because they are not going to be enough. But also that by seeking a high level of happiness will make it more difficult to be happy because you are going to disregard small good things.
