Isn't something extra good?

We have seen a saying that nothing is too good. Doing anything extra can cause you a lot of damage or you may even lose everything. To overdo it is to take extra risk which is very harmful for you.

Let's say you are doing a business and that business is making a fair amount of profit. Now you are going to do something extra in the hope of profit and it has a lot of ricks but if you are going to do that work then will you be successful or everything may be lost. So I think we need to be content with what we have because excess is detrimental to everything.

Then let's say that you are spending extra time with someone and that person must think of you as an ineffective person because you showed up there as soon as you were covered and you never said that such a valuable person is not worth it. So you don't try to do anything extra which can be harmful for you.
