Greetings of the day from Siddhivinayak Solutionss!!
The answer for your question is no
If you are working hard and not able to achieve the desired results then you should check what is going wrong
We should believe in karma as karma and luck are inter-related to each other
If you depend on luck by living on luck then you will not be able to do anything in life
But it is fact that whatever is given no one can take from you but if you improve your karma that is present then the future can be bright.
