Nobody chooses to evolve. It's like floods and avalanches and earthquakes. You never know what's happening until they hit, then it's too late.

You may work with 100% capacity every day and may not be seen by anybody for recommendation. This does not mean you should give up! The day you will decide to work at 40% may be the day you'll be seen by the person who is meant to recommend you for higher profile opportunities!

If you want to double your productively, shorten the timeline to by 50%.

Five people with passion can do better than fifty people with mere desire or interest.
