Don't tell people about your goals. Achieve them.

When you tell someone about your goal, you already feel partially satisfied because you start thinking that you’ve done some steps on the way towards your goal.

Plus, some of the people you tell might demotivate you.

Having an all or nothing mentality leaves you with nothing sometimes. Have a clear vision for what you’d like to accomplish but include learning something new in your goal.

If you always aim for improvement and learning, you are much less likely to fail.

You work with a variety of people and you won't always get along with everyone. Telling yourself, "I don't engage in office politics, I tell it like it is," is a flawed tactic that might just cause more trouble.
