That idea you have? Stop putting it off. Will it be difficult? Probably. Will you want to give up? Absolutely. But don’t. You have to persevere.
What about failure? Learn from it. Try again. Be smarter this time. Make new mistakes. There’s a story I heard once: it took Edison more than 1,000 tries to invent the light bulb. He remarked to a reporter that he had not failed, he had simply found 1,000 ways to not create a light bulb.
How about luck? You’ll need it. But don’t let that stop you. You can’t get lucky if you don’t even try.
Get started. Change something. Do something.
