Always bear in mind that your own resolution to succeed is more important than any one thing.
If A is success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut.
Of course there is no formula for success except perhaps an unconditional acceptance of life and what it brings.
I don't know the key to success, but the key to failure is trying to please everybody.
Real success is finding your lifework in the work that you love.
