What are some important things in life that should be left to destiny?

Death.  Being mere mortals, death is something that will inevitably happen.  It can happen naturally or unnaturally, but it's something you can't really control.  You can extend your expectancy, but its only what you expect - not destiny's expectation.  Live each day like it is your last!  Carpe Diem!

Nothing should be left to destiny, however everything is destiny. I know the statement sounds very complex but thats the reality of it. The first part means that one should never simply back off from things because they believe in destiny. No, as a human you should put your utmost effort into the matter. The second part means that once the effort has been made, it is now a matter of time and or destiny to decide. If you get it, good if not then dont be let down.

Universe is beautiful and mysterious in itself . The way it functions nobody knows, and we never we want to know it too. It showers gifts on each and every person. The lucky ones are those who can see the opportunity in and around them. Those lucky ones live their life as it comes with zero worries. And tomorrow is always better than today.  Hope is the fire in their soul. They know that how much ever they care about anything, they cannot control all of the events happening around them. So they are wise in that they move elegantly with time. We can  say that,  not just specific events,  but everything shouldn't be taken too seriously. Life is meant to be swiftly lived. Live hassle free without expecting.  You will always fare well this way. In the end all that matters is how joyfully and meaningfully you lived. Sing. Dance. Listen to http://music.Do adventures. Travel to  far lands. See people. Enjoy solitude. Eat delicious food. Love.

(1) paisa toh haath ki mael hai... Urdu/Hindi proverb: "Money is the dirt of one's hands..."-- ie: whether wealth comes or goes, dont obsess over it's presence or lack, similar to your hands getting dusty when you work. (2) kisney kitna bhogna hai, aur kisnay kitna jeena hai... sab upar waalay par chorh do... Urdu/Hindi proverb: how much one will consume (ie: eat/have sex/rest) and when will one die-- leave it to the one above (ie: God). Ie: dont be scared to die or overly focussed on avoiding death; and dont obsess over how many or how few monetary rewards you have got.

To choose on 'What to be decided by destiny' should be left to destiny itself, if you are meant to find it, you will find it.. else, don't bother, not much fun.. Life is not worth worrying at all, coz, no man, be it billionaire or a pauper is free of troubles.. all humans, each one, has his/her own 'big' battle to fight.. there is nothing to worry, forget it, what is destined to happen, will happen, no use to worrying or fearing, as it would be changing nothing.. rather start working on what you feel comfortable and adapt to change.. Just keep doing what you feel good..

I'll left my thoughts consist of myself as destiny. For the ideas and thoughts are made by, or taught from the society (it depends on which community you grew up, what kind of people there are in your teen-age.) and the elder people's experience. Although using rational minds you can choose what is for you or just for the others. You can't really choose your parents who grew you up, and the environment to live by in an early age. I find myself like a monster eating and digesting what were told to myself. Still growing bigger and stronger than ever.

There is good reason to believe that all things in life are left to destiny, but it seems to make no sense in our current understanding of things.  My advice is to take control of your own life as best you can.

May be the consequences of everything we do should be left for our destiny to decide..yeah i do agree that destiny is something..I have heard people saying that it's all about you..how you perceive things and work to achieve them...that's very much true...but somewhere down the line..what if something unexpected happens..something goes wrong..this is where you cannot do anything about it..all you have is that hope which helps you to revive your faith in yourself  and start afresh..so just keep working hard and leave the rest to god..efforts get paid :) :D
