We fear simply because we are not living with life — we are living in our mind. Our fear is always about what's going to happen next, which means fear is always about something that does not exist, and is therefore 100% imaginary. The normal cause of suffering due to fear is either what happened in the past, or what might happen in the future — and neither of those exists either.
The mind has two parts, memory and imagination, and neither exists in the present — memory belongs to the past, imagination to the future. Fear is an outcome of suffering caused by either. It's like the mind creating horror movies: fears are stories that we tell ourselves.
Sometimes we get too biased by our own mental creations — our thoughts and emotions — and forget that the Almighty's creation is much stronger than our perceptions. We should try to divert and master our mind to live in the present, which is reality: live your life now, since there is no greater phenomenon than life itself. If we do our present well, our future will naturally blossom.
Take life easy — take it non-seriously, yet stay involved with it, the way we do when we play sports. Be a sport for life. If we truly care about what we want to do and it really matters to us, life becomes worthwhile, and our existence meaningful, irrespective of what we achieve.
