One day you'll truly grow up and those things you crave now will be obsolete and those thing you missed in life, due to your current cravings, will become important to you.
This is not to say than achieving a goal is not important bun remember the verse in the bible than says:
It will be easier for a camel to pass through the eye of a needle than it will be for a rich man to enter the kingdom of Heaven.
Give it a thought or two, always count your blessings, and when life turns on you, and it will, remember how important the simple things in life really are and how brief a stay we have here on this rock we call earth.
