求一个英语谚语的评论A bird in the hand is worth two in the bush.给这句谚语评

The saying "A bird in the hand is worth two in the bush" teaches us something.It tells us what you grip in hand is the most important.What you desire of but haven't possessed never counts.When one really understands the meaning of the saying,one will know how to deal with the dilema of life.Life is full of choices,but we should think twice and get the most out of what we already have in hand.When we are lured by other seemingly wonderful things in life,we shoul cherish what we have obtained and be wary of risk.
