When you say that my job is guaranteed and that you will be successful in any case, you may become complacent about working and fail suddenly, and this will break all your hopes.
When you say that you can never do it and say that you will never be successful, you will perish in pessimism.
For these reasons, you should be prepared for everything in your life.
When you make this balance your philosophy of life, you can be happy in success or failure.
I wish you to be between hope and despair...
