"It’s easy to see how little launches matter. Think of some successful startups. How many of their launches do you remember? All you need from a launch is some initial core of users. How well you’re doing a few months later will depend more on how happy you made those users than how many there were of them."

How do you keep yourself motivated to practice?
Anonymous

angrykoreanguy:

fuck motivation. it’s a fickle and unreliable little dickfuck and it isn’t worth your time.

better to cultivate discipline than to rely on motivation. force yourself to do things. force yourself to get up out of bed and practice. force yourself to work.

motivation is fleeting and it’s easy to rely on because it requires no concentrated effort to get. motivation comes to you, you don’t even have to chase after it.

discipline is reliable, motivation is fleeting. the question isn’t how to keep yourself motivated, it’s how to train yourself to work without it.

"It was in my laptop bag. It’s made of gold, so it absorbs all the X-rays—it’s completely black. And they had never seen anything completely black. “They’re like, ‘Sir, there’s something in your bag.’
I said, ‘Yes, I think it’s this box.’
They said, ‘What’s in the box?’
I said, ‘a large gold medal,’ as one does.
So they opened it up and they said, ‘What’s it made out of?’
I said, ‘gold.’
And they’re like, ‘Uhhhh. Who gave this to you?’
‘The King of Sweden.’
‘Why did he give this to you?’
‘Because I helped discover the expansion rate of the universe was accelerating.’
At which point, they were beginning to lose their sense of humor."
