Detachment is the only way to go forward, whenever you are suffering in life, just remember these sentences from Lord Buddha ” The root of suffering is attachment”.
Have it in your mind always, and you will have a good life.
Life gets tough when we are attached to the outcomes, which are not in our hand, so we should avoid getting too much carried away with the results, we can just sincerely try to get work done, but its ultimately in the hands of the divine to give us the result, and in case if you do not get satisfactory results, remember that everything happens for good.
Life has many ways to grow, and if your plans are not working, have faith in gods plan, they are best for all of us.
Wish you a happy life!!
