How do deal with dreams continuing to be crushed

" “People die everyday. Washing dishes. Mopping floors. And you know what their last thought is? I never got my shot.."  - Million Dollar Baby.

Crushed dreams. 

Is there any escape from this?

Who put the dreams..the ambition in our head anyways? What is the scent that we pick and chase this dream? Each dream that I have chased have always had a beginning that seemed to indicate that the universe favoured this move. And yet, as I work towards this, it becomes elusive. Its a scary place . to be right in the middle. Where each time you want to give up and make a fresh start, some other breakthrough comes and you go back working again. As though the moment you decide to drop it, something in the universe wants you to continue. Like being condemned like Sisiphus. 

When then give those dreams to chase? It chills my spine when I read about people who worked hard all their life but did not get a break to making riches while many made their fortune quite by accident or without much effort. Like they did not get their "shot". 

Will I die like that? With all my dreams unfulfilled and me really not seeing that I dont deserve to make my dreams a reality but contine working for it? Gita say inaction is not an option. Struggle but without anxiety or agitation. 

When can I stop running and plant a seed that I can harvest and rest? Even though I try to see the laws and act according to it I dont get any where. Which is for me the cause of loss of faith. WHen the law does not operate "as I thought it would". Loss of faith also comes when I compare my fate with others and wonder what wrong did I do to deserve this? 

But what is the way out of all this ? Not dreaming or creating a cause for action will render me passive. DOing things as a duty will always help to do an action without desire. But how do I hold the forces of life - the rent cheques, the school salaries..from eating me alive? If I am responsible for my family's welfare how can I not fight back to make sure they have a roof over their head and food on the table? 

If I have been given intelligence and ambition I have to work with what I have. My intelligence comes in my way of God wanting to help me because my intelligence keeps trying to give me solutions. And till I stop tired I will never get help from GOd. But inaction is not an option as Gita says. Also I am scared to strop struggling and trying.

If I do end up on the death bed, and realise that I did not get my shot - how will I deal with it? Should I stop dreaming and instead look at my life completely differently? Like its not mine to be lived? I follow my dreams..and when they get shattered..watch the material called " disappointment" or "feeling crushed" or "beaten down" being created. Then slowly as I watch it will find that material no longer gets created. Something will die inside me. THen I will go through the motions of life. Compromise and say maybe this was meant to be? Or maybe find a meaning in life by just chasing my dreams and not about their fulfillment. One dream after another. 

So when I die, I dream about what to do next?
