Have a look at a book called "Getting results the agile way". It's a simple process which you could probably glean from reading the introduction. Essential you choose 3 things each day that are important for you to solve, 3 things each week, 3 things each month.. You can see where this is going...Or as a quick (great way) to boost to your productivity have a look at the 'pomodoro technique' There is also another great book called "Getting Things Done" but that takes much more effort and takes a somewhat anal approach to managing every conceivable thing if your life.
