Yes 7

1. It will take longer;
2. it will be tougher;
3. 'hero on a journey' is an understatement;
4. only one or two will encourage;
5. there will be one very dark day indeed;
6. coffee will start to taste unpleasantly bitter;
7. you will hallucinate in your desire for a break.

But it will. Eventually. Be worth it.
