Common advice in regards to women on here is to achieve an abundance/"fuck you" position where the potential loss of any one of them won't get a reaction out of you beyond the optional "oh well that's too bad". That attitude in a situation of abundance isn't limited to women though, it applies to all things in life. Especially time.

Ever notice how you get increasingly productive the closer you get to a deadline? That's because you're becoming acutely aware of your remaining time's value towards completing your task, which increases the less you have of it. Procrastination and lethargy are basically side effects of being a time millionaire. You perceive yourself as having all the time in the world and thus you don't care about wasting any of it. This is why when you want to actually get shit done, you have to fix yourself a deadline.

Good time management can be summarized in two simple rules: have a long term deadline for final completion and short term ones for intermediary goals building towards that completion. The reason why it's essential to have good time management is because whenever you set yourself an objective, your mind becomes your personal defense attorney in acquitting you from doing shit now.

If your objective is learning to speak Russian, as soon as you get to the boring grammar shit all your mind has to do is show reasonable doubt that you'll eventually get to doing it in a nebulous future to get you to stop. It's a perceived win-win for you because you'll both supposedly still achieve your objective and you don't have to do the boring shit right now. If however your long term objective is learning to speak Russian within the next six months and your short term one is getting through a chapter's worth of the grammar shit within the next day, any delay or postponing automatically works against succeeding within the allotted time, removing the win-win situation.
