A huge portion of success is showing up. Some people think that they are better off not showing up. That is a strategy that will lead to failure. When you don’t show up, you are seen as unreliable and as a liability. It actually creates barriers to your success. People will not do anything for you if you build up a reputation like this (Exception: They will recommend you not be considered for a job or promotion).
Showing up means a lot, even if you are not the best. Once people know your strengths and weaknesses they will compensate for your weaknesses and help your utilize your strengths. Most people you work with will want to see you succeed.
Show up, it might be the best decision you ever make.
