You were born with nothing, and you will die with nothing. You are not your body. You are the eternal soul, which is immortal.
Goal is to refine yourself in this iteration (of life) and become a better self.
Everything is temporary, as far as you are concerned, from your perspective. Think again, "Everything is Temporary". You are here for a short duration. Do you know, where you were, before you were born? Or, where you will be, after you die? Bhagavad Gita answers this question beautifully. Verse 2:12: "Never was there a time when I did not exist, nor you, nor all these kings; nor in the future shall any of us cease to be."
You will go through endless cycles, until you are fully refined and you will then be liberated from this continuous cycle of Birth and Death.
Do not feed your senses. They will interfere with your spiritual growth. You were not born to satisfy your senses, the goal of birth in this life is to refine yourself, make yourself a better person - an evolved being.
Result of any work is not important. What is important is, with how much dedication was the work done? All honest, selfless, dedicated karma will refine you. Note: you cannot take anything with you when you die, except for yourself, your soul. Hopefully, you have refined yourself more, during this cycle/iteration of life.
Be free from all attachments, fear and anger.
Maya has been created from "Lust".
