Smile more yes smile more,smile will make you achieve anything,but stress is there,it will kill you from inside and outside.
Stress can be of any type,it is from study pressure or from other reasons,but there is nothing to worry from it,just believe in yourself and do your work honestly,never get demotivated from failures.
Stay positive and stay cool,you will feel good and achieve everything u want,if there is no struggle,there is no gain.
If there is smile,there will be no stress.
