"Things I wish I'd known at 20: Your time is worth $1000/hour, act like it"
Actually, for most 20 year olds that's not true. For me, for instance, it was absolutely a good tradeoff of time and money for me to catch a train to the airport, taking 1 hour and $10, instead of catching a $50 cab for a half hour trip (therefore, I am saying that half an hour was worth less to me than $40). Clearly he meant this 'metaphorically', but when your metaphor breaks down so easily, it might not be as meaningful as you thought. What did he actually want to say there? Was it something less pithy like 'value your time'? 'Consider the opportunity costs of everything you spend time on'?
Lets say that 30 minute cab ride cost an additional $40. If your job is paying you $8 an hour then you have to work an extra five hours for it. Taking the bus didn't cost you half an hour, it saved you four and a half.
My best time management hack was replacing my todo list with a calendar. With todo lists I tended to put things off for later and never got everything done. With a calendar I'm forced to commit to a specific time.
It's missing one slide: "it's more important to be happy than productive". Crossing stuff off your TODO list with maximum possible speed is not the end goal in itself.
lol. I can be happy if I'm resting, but not if I don't feel I'm currently achieving much. Direction, purpose, identity, creation of meaning for the self, that kind of thing.
The biggest hack I have was using 20 minutes countdown clock like http://e.ggtimer.com/20minutes. And it must be easily accesible from the Bookmarks toolbar so I can easily select 20 minutes, etc. and then get going. I think this relates to point #7: "We're always more focused and productive with limited time". :)
The simplest and easiest way to get more important things done:
Ask yourself three times daily, via Outlook reminder or whatever is convenient:
"Am I inventing things to do to avoid the important?"
This is from the book The Four Hour Workweek, an excellent, excellent book. I've listened to it twice now (26 hours). This book has changed my mindset and has made me much more efficient and effective at work, and life in general.
Also suggested in the book, time tracking software like rescuetime.com or Manic Time is extremely eye opening. It was astounding how long I was spending writing emails. Now I have various email templates for common issues I face. What a great book.
The key to productivity is to harness procrastination: Always have something else to avoid, that makes your work seem like procrastination. Make up a dreaded obligation, so that work for your other goals is seen as an escape.
The only one I don't agree with is 21 - "Yesterday's home runs don't win today's game".
Whilst you can no longer do anything about what happened yesterday, it can still have a huge influence on how today goes, particularly if you spend much of your day influencing other people, and you often need to keep that in mind.
E.g. - I'm preparing for a presentation with a director - did my last interaction with him go well? If not, I'm probably going to have to work extra hard at getting my message across.
Unfortunately a lot of people don't seem to get this and treat pretty much every interaction as a self-contained thing, not realising what effect existing preconceptions will have on this interaction, and not really thinking about what impact this interaction wil have on future ones.
But yesterday's home runs may well have a psychological impact on both you and your opponent in today's game.
Not resting on your laurels is fine, but putting what happened yesterday totally out of your mind when you come to today's game/task isn't always the best thing to do.
Eliminate - Is this really needed to be done? What if I just don't do it?
Delegate - Do I have to do it? Is it ok if someone else does it for me?
Automate - Will I have to do this again? If yes, can I automate it?
