Excess is by definition bad. Too much of anything is as bad as too little, that's what "too" means.
Any wise or happy person will tell you that the wise path is the path of moderation. Moderation means deciding for yourself what limits to set. As humans we seek universal and extreme rules such as "You can't get enough of X." or "Always do this, when this happends".
There is no "always", "never", "can't", "should"...
