Build a strict schedule and stick to it.
Assign some days to certain types of tasks.
That's what helped me. At first it might seems like monotony but it isn't, a strict schedule can have some flexible time.
It also forces you to do the things you have to do, you don't lag off.

I thought that after university I'll loose all my free time but it turned out the other way around. Get a hold of the mastering of time management.

How my personal TODO list and schedule are split:

The TODO list:

My todo list is split up into categories which are:

* The must do stack (with little things, dates to remember, and a lot of little notes)
* The Days counter (a place where I count days for things I want to keep doing)
* Learning (a big list of links and notes about things I want to read about and learn)
* Projects (A list of projects ideas I'm working on or willing to start working on)
* The daily (Some stuffs that I don't look at too much because I do them daily, but in case I forget)
* Goals (A list of goals, long term, mid term, and long)
* Notes (A bunch of notes about random things)
* My 2-3 motivational quotes (To remind me when I'm slacking off that I should keep going)

Remember that everything is flexible.

I had a strict schedule when my commute was taking 2h to get to work and 3h20min to get back home, waking up at 5am and reaching home at 7:20pm.

You can manage it. Men have great willpower!
