Hard work is a necessity in life if you want to get anywhere. If you want to make money, then you have to be prepared to work for it. If you want a relationship to work, then you have to be aware that give and take are required. If you are building or making something, it will not put itself together and you have to be prepared to make the effort to do it yourself.
Although the rock hard abs you are looking for can be achieved somewhat quickly, the truth of the matter is that this process will never be instant. You are a human being with a human body. You can't just think yourself thin, wish more hair on to your head or make your legs longer with the power of your mind. You need to put in genuine work to achieve self-improvement.
If you are told or advised that you can have the abs you have always dreamed of in just a couple of days with no punishing work, then you ought to be aware that this is an outright lie. Sometimes, it is best to be honest right down the line. You will have to work to get better abs – how else are they going to happen? - but if you are smart, the amount of work may not be as punishing.
Impossible promises are not uncommon on the internet – look at the spam folder in your email for absolute proof of this. They are a bid to draw money out of desperate customers who feel that they have exhausted all of their options. Don't fall for them, and be persistent.
