When you are stuck on something, do something which can inspire you, give new energy to push for the success. Even if it doesn’t work, think about something glorious you have achieved which you initially thought won’t be possible but eventually you did it. This is you who needs to believe. No one.. yes no one can help you if you can’t help your self.
No one is going save you when you you are in shit if you are not extremely lucky. This is you who needs to save your own ASS. Just mind it. Never keep any expectation. If you get anything, that is bonus!
