There is a short saying. People often say Mark Twain wrote it. He was an American writer. The saying is: "The secret of getting ahead is getting started."
This sounds too simple. But think about the last big task you had. Maybe you cleaned the whole house. Maybe you wrote a report. The hardest part is often not finishing. It is starting.
The saying gives more advice too: break your big task into small tasks. Then start with just the first small one.
For example, a student needs to write a long essay. She does not have to write it all today. She can open a page and write one sentence.
This one small step makes the rest easier. The task does not feel like a mountain anymore. It feels like a path, one step at a time.
