What lights you up??? That is what you get to share on this planet! Choose to share and as you take the steps go and do your work. Don't give up prematurely, and don't forget to build the tower or protect your work!!!
The Parable of the Servant who planted the Olive Trees (Doctrine & Covenants Section 101).
Have you ever had a good desire (to write a book, make a blog, record a podcast) for growing and improving your life, finances, and relationships, only to start but not finish??? Every goal has a certain gestation time. If you start taking steps toward the goal and then give up before fruitation, or don't nurture and protect the work you have.
When going through a hard time ask "what is there to learn?"
What could my life look like? Continue on the path! Pick a direction and have constant, steady movement in that direction! This is where joy comes in!
