Being well-rounded is a myth.
You have the gifts, abilities, passion, and experience to do very few things well. For most people, there is only one thing they can do with skill.
Most of the great musicians you know are not skilled at art with oil or clay. Very few artists are great at accounting. I don’t know of any accountants who excel at public speaking.
Michael Jordan was not a great baseball player. Tim Tebow was a below-average professional baseball player too. They were both excellent in their roles as professional basketball player and college quarterback.
The challenge in life is to find the area where God has gifted you and do it well.
I must continually remind myself that it is okay not to be well-rounded and waste my energy in areas where I will never excel. People are most blessed when you do your one thing, as only you can do it. I thank God that Da Vinci focused on his art and not accounting.
If you apply yourself to one thing, I believe people will thank God for you using your skills for his glory.
