An individual have immense potential the only need is- to identify it and channelisation of all the energy to achieve the goal.
Everything is possible in this world and whatever the acheivements we are seeing all around us has been achieved by the human being.
So, set your target and go for it. Think about it every time. Eat it , drink it and sleep with it. This will energise all the body and align your all the activities to achieve the goals.
Do meditation and take out the positive energy from you which is stored inside. Don't think about failures. Failure happens and will happen but no doubt, if you are ready to failure and this will not bother you, you will definately win and win.
