If you want it then you will do something about it, you will do everything to get it, as simple as that.
The reason why you can't pull the trigger and take the necessary actions to get your dreams is because you really don't want it. You think you want it but when the going gets tough... you will make an excuse that you really don't want it, you will make yourself believe that you want something else. You are fooling yourself, you are selling yourself short.
If you want to hit your target then first, you must know it. You must know what you are trying to hit and hit it as hard as you can.
You can't pull the trigger because you're scared. It's not that you don't have the means and knowledge for getting it, you're just scared, as simple as that.
If you really want it then you should start hitting it now, aim then fire, pull the trigger. Make it yours, own it and never let it go.
The only thing that should be on your mind is your target and nothing else. Keep your focus very sharp and never blink for a second. Never lose hope if you have bad misses, it is normal, you will become better as you keep trying.
Keep hitting even if your are missing, you will hit in in just a matter of time, use the law of averages. Never stop until you hit it.
Once you made a decision that you are going to hit it.... keep trying until you hit it. Forget about the consequences, forget the obstacles on the way. You will only be able to hit it if you have a laser like focus.
Never get discouraged if you already missed a thousand times, you only need to hit your target once, once is enough to become successful. So keep hitting until you succeed.
