‘Focus’ on your long term passion that has been discovered via experiments run over many years. Have the ‘persistence’ to not give up when the going gets tough.
Research has shown that the #1 predictor of long term success is Grit. Not talent, not IQ, but grit. And having grit does not mean machoism and denying pain. It is knowing the pain, understanding it, sharing it with others, finding the immediate next step and making progress.
When this resilient progress is combined with a clear and consistent direction i.e ‘north star’, you can achieve anything.
