Answer 3

Don't write the code for yourself, write it for other people.
Comment and document as much as you can, give variables clear names, have stucture in your code and use new lines where they make sense instead of keeping your code as short as possible.

Answer 4

Make sure you completely understand the task your program is going to perform!
This sounds like 'duh', but actually if you are even a bit confused about how your algorithm should work, your code will also look confused.
After you have whittled down the series of operations to the minimal number of necessary steps, you have a chance to write an efficient code.
If you then add telling names, good formatting and comments only where it's absolutely necessary, it will probably be good.
