Absolutely not; there is always hope. Yet sometimes hope is hidden in these so called most unfortunate events. I survived a 30-day comatose state and came out better for the experience. You can read about it if desired, at my hub titled, There and Back (Version Deux).
The life of Steve Jobs is one of many losses that soon became blessings for him. His mother was a college student and unmarried when she carried Steve to term. Steve was born only to be given up for adoption; yet the couple that was going to adopt him refused to adopt him because he was male. His mother could not keep him because of her father's refusal... His mom scrambled to find another couple. A couple who had almost lost hope they would ever have a son to raise found out about this baby and completed the paperwork, interviews and eventually convinced Steve's mom although they were uneducated (the adopter dad was a Military Vet. He was a machinist-keep that thought, in the Military and his wife was unemployed).
Yet they loved Steve. Steve was raised well by his mostly uneducated parents. His dad transferred his machinist knowledge to Steve. So Steve and his friend tinkered in his dad's machine-shop garage and eventually housed a CPU in a smaller machined housing. That would indeed be the Apple IIe forerunner and Apple Computer had its genesis thanks in part to his adopted dad.
By age 30 Steve would be fired from his company by the Board of Directors that had come to power. Steve was shocked, bitter, in disarray yet he eventually accepted it. He still had hope and love for computers and if I may add computer animation so he formed another company that was called Pixar.
His Pixar Studios was eventually bought out by a company that was started by another guy who was previously fired as a newspaper writer and told he had no imagination. That guy was Walter Disney!
Steve also came up with some invaluable hardware that Apple required and paid him dearly for it and brought him as an advisor/board member. They paid him more than he was making as a part owner.
Now Steve did indeed eventually succumb to cancer and lost his life. Many would say much too soon and it is so sad. Yet just maybe this Steve was still holding out hope for something beyond his life and it was indeed his time (finally)... There is more to text; yet I am out of character(s) no pun intended... Therefore, let me end with this statement. Your firing will become opportunity that was or is hidden from you. Pray about it and listen, listen, listen...
