Well, time management is to make things easier and clearer, not to make trouble.
Schedule your work list and set up the deadline, then do per the work list.
I think time management is really really easy, you just need to do it right and do it now. Don't waste the time on the list or schedule or plan, no perfect schedule, we will be experienced during the process.
My secret is: focus on one thing one time and put the others in the quene.
And id nesessary, you can find help from online to do list app, such as TABB, HiTask etc. There are so many.
