If a religion wants you to give up your freedom, just give up that religion! Nothing is holier than your freedom!
Solving a complicated problem can be frustrating. You can have good problem solving skills, but sometimes a problem seems like it has no solution. Nevertheless, never give up.
Never give up the life you wish, because that wish is your personal sun! If you give up, you will find yourself in the darkness even in the brightest day!
Never give up fighting against the universe because we exist in life through action, through fighting!
You want to be a river? This is not necessary because you can be a river without being a river; just flow in your life, this is what the rivers are doing, they are flowing! Remember, you can be anything without giving up yourself. Never wish to be something else, always be yourself! You want to be a Sun? Just give warmth to everyone with kind words!
