Have a purpose in life. May be, have someone as a purpose of life. It gives direction to life. The biggest obstacle to this is the fear of what if the choice we make is proved wrong. Don’t let this fear come in your way. It is not necessary to know or do everything. All scientist may not be able to make a breakthrough invention. All sportsmen may not win tournaments. All painters may not become Picasso. Still, the satisfaction of making your own choice and pursuing it will give you the much needed meaning in life.
