To achieve means to attain, to fulfill or to realize something. So achievement starts with a goal, a vision or an end in mind. Therefore to achieve means to attain your goal or vision.
The question now is what do you want to achieve? The reason for this question is this; you can only achieve what you have ability to do. For example, what can bird do? Bird has the ability to fly. The goal of a bird should be to fly the farthest into the sky. The day the bird can do that, it has achieved it goal.
The point I am making is that the design of an object determines the function or what the object can do. So the first step toward personal achievement is to discover who you are, then you will discover what you are designed or wired to do. The bird knows it has been wired to fly. Through training from the mother bird, hard work and patient the bird will fly, but no amount of training, hard work or patient can make a bird to swim like fish.
Take a time today to discover who your are, then you will discover what you are designed or wired to do. Afterward, acquire the best training you can afford, do your best and with time you will be the next achiever; another man who has done what he has the ability or potential to do.
