Don't stop. Do whatever you are doing. Your destiny has already defined. All the ups and downs you see in your life are just forces which are directing you in a right direction. Every individual in this world has taken birth to fulfill a purpose. All you need to have a little faith in HIM or in yourself( there is absolutely no difference). Don't expect the next moment just focus on this very present moment. Follow this simple path and in last you will not get what you always want or your uttermost desire but Everything.
PS: you will see the universe via naked eye.
