“Here’s the point: You get out what you put in—to a degree. Your natural ability and strengths play a big role in determining the potential of your output. Don’t work on things that don’t play to your strengths and passions. Don’t work on things that provide opportunities that don’t interest you. It’s easy to get lost in the fight, and continuously bang your head against the wall when people tell you that you get out what you put in. That expression tells us to just keep working harder, regardless of the task. This isn’t always the answer. If you’re working hard and don’t feel like you’re getting out what you’re putting in, you probably need to stop banging your head against the wall and jump ship. There is also a time factor here, which is very important to consider. YouTube was acquired by Google for $1.65 billion in 2006, less than two years after its founding.[28] PopCap, a gaming company, was acquired by Electronic Arts for $750 million in 2011, eleven years after its founding.[29] If you founded or worked for either of these companies and loved every moment of it, the difference in time-to-acquisition is a non-factor. But, if you did not enjoy yourself and didn’t grow along the way, you better hope you were working at YouTube. Two years of stagnant personal growth is far less painful than eleven. The example above includes two companies that both sold for a bunch of money, which is great. But there’s more to life than money. There’s an opportunity cost to everything you do. If you’re hitting a wall for more than a year and you’re unhappy, I recommend jumping ship—even if there’s a potential pile of cash down the road. There are opportunities beyond whatever you’re currently working on. Forget how much time, effort, and money has already been invested and ignore whatever you might be giving up if you leave. Those are sunk costs and unknown outcomes. Instead, think about what you’re working on and who you’re working with right now. Then decide if that’s really how you want to be spending your days. That’s all that really matters.”
