Reliable.

You simply can’t count on your other handicaps to hold you back if you persist in being reliable.

Charlie Munger’s prescriptions for misery in Harvard Commencement Speech, 1986
Reliable: Able to rely upon.

Are you reliable? 
If yes, great! You can skip today's post. 

If no, then why not?
The intention is not to make you feel guilty. That's useless. 

But to make you think objectively: Why would you not consider yourself reliable?

Mostly our identity of being unreliable comes from our tendency to say 'yes' or make commitments casually. 

To others, and especially to ourselves.  

Obviously when we do that, we don't live up to these commitments. 

Consequently, we start building an identity of being unreliable. 

You can start becoming more reliable by being extremely selective of the things that you say 'Yes' to. 

Saying 'No' is the starting point of becoming more reliable.
