I remember my college professor who says, first choose a field for your life then you should very much skills in your field even your field is repairing the tyres of bicycles. No one the world should have skills equal to you in your field. These are much valuable advices that we should focus on one thing. it does not matter how small this thing is. we should have highest skill in one field not a non-skilled Peron of all skills. It is gladdest movement for me to hear a legend.
