Don’t announce you’ll do something. Just do it.
I remember when I went in for a job interview. I answered every question very well and even felt the vibe that I already had gotten the job. I felt so confident about it that I just had to tell a few friends about it and even started thinking about my life at that job.
Then, after weeks of hearing nothing from the employer, I learned that someone else got the position.
I remember when I told people that I’m going to start losing weight. I didn’t.
I remember when I told people that I was going to start redesigning my site. I haven’t started yet.
Instead of telling people what you’re going to do, just do it. When the task is done, that is when you can announce your thing.
