Here’s what I believe about starting and finishing.
It’s good to start things. You should start a lot of things. Starting things is fun and, if you’re wired that way you shouldn’t stop.
And, once started, it’s okay if not all of those things see the light of day. Over time, you’ll drop some stuff, you’ll forget some stuff, you’ll let some stuff fall to the side. That’s okay.
You need to try to get more of those things to a finish. Sure, you don’t have to let all of them get to a finish. But you need to take a look at what you are starting and what you are finishing and you need to decide how to bring more of those things further along.
And, you need to get better and purposely stopping things rather than just letting them fizzle out.
You need to start well, with a good plan, and plenty of contingencies forecasted. You need to move forward, stepping up your game as the project becomes harder and harder to accomplish. And you need to become addicted to the finish and embrace the feeling you get when a project wraps up successfully.
Make stuff. Do stuff. Build stuff. Have fun doing it. And try to finish what you start more often.
