Time management is not a problem for me, in my opinion it's just a way to organize your tasks to make job done.
Key element of time management is to define priorities - what you have to do in the first place and what can be done later. Make a schedule; think what part of your work you can pass to somebody else. Why not?
To be more specific my time management looks this way:
I divide tasks into three categories:
A - what should be done urgently (high priority).
B - what can be done later (medium priority).
C - what can be passed to somebody else or may be cancelled (low priority).
Then I make schedule and do it one by one.
And, of course, strong will is essential.
That's just my own way of time management I use to succeed.
