Desire- it's a useless emotion? or a emotion that can propel us into great action?

Desire...is it a useless emotion? or a emotion that can propel us into great action? or a emotion that can be very nasty if left unattended.

From what i can understand,desire is a useless as well as useful emotion that can be utilized to make our life for the better.

For e.g. if you desire to be beautiful in the physical sense of the word and the reality is that you are ugly,then i am sorry to say whatever you do to reach your perfect beauty,it won't be enough because you are lost in the physical beauty.
Beautiful is the one whose actions are more meaningful and beautiful.period,if you are not satisfied with this answer,go ahead with your makeup and cosmetic surgery.

It is my desire to let go of the desire that i am incomplete without a person of opposite sex, that i am not beautiful physically,not appealing.
It is my desire to make this planet more liveable and take actions to make it so.(Because in all fairness ,merely wishing it,won't make it happen).

You have to understand that sometimes having unrealistic desires can wreck havoc in our lives,
For e.g.the perfect mate,the perfect house,the perfect kids,the perfect job,the perfect life.Now look around you,tell me what do you see? you may see what you want to see,you understand? you see what you actually desire,you may see that someone may have the perfect all of the above,but trust your inner instinct,they don't have it.

Grass always looks greener on the other side and it tastes sweeter too.

You have to be gentle with yourself,you have to remind yourself that ,"whatever i will work for -i will get it,nothing more -nothing less".No unrealistic wishing and desiring business here.

So work Hard ,Think Smart for Fulfilling your desires.

You Get What You Put In.
