It is extremely important to dedicate time to intentionally define success.
And while doing that, you have to consider the difference between success that is dependent on your own actions and success that is dependent on others’ actions or environmental circumstances.
Say you want to write a blog post a week for the next year.
Actually writing a blog post a week for the next year depends pretty much solely on you. You should have started yesterday, you could start now, you can do it. It is up to you.
Getting people to read your blog post every week, having an increasing audience month after month, closing the year with 1,000 people registered to your newsletter. These are all things that do not depend on you. Of course, you can try to influence those, but truth is you have no idea if any of that is going to happen.
So, when you define success make the distinction.
That does not mean that finding an audience, increasing your list, getting your content to more and more people does not matter. It is just out of your control, and it should never be the primary driver for your doing.
