Lead where you are strong, and build a team where you need help. This practical wisdom is sensible advice in the workplace and in your personal life. Many people spread themselves too thin by trying to do things for themselves that are not actually in their primary skill sets. A better plan would be to find someone you can depend on for those assignments that do not lend themselves to a do-it-yourself approach.
One of the joys of growing older is an increasing self-awareness about what your strengths are. Another benefit of maturity is a more discerning eye when it comes to surrounding yourself with a team of excellence. Through trial and error, or word of mouth, you will learn over the years which professionals you can rely upon for help.
