You will surely wear out, both yourself and these people who are with you, for the task is too heavy for you; you cannot do it alone. - Exodus 18:18.

President Theodore Roosevelt once said:

The best executive in the one who has sense enough to pick good men to do what he wants done, and self=restraint to keep from meddling with them while they do it. - President Theodore Roosevelt

Bottom line: Unless you learn to delegate, your leadership will deteriorate and your vision will stagnate. In Exodus Moses was wearing himself out, physically, emotionally and spiritually trying to keep up with the demands of the fledging nation that of people that had followed he and the Lord from Egypt. He was trying to be 'the answer man for every problem. That's when his father-in-law told him (verse above) 'you cannot do it alone!'.

It takes wisdom, maturity and humility to ask for help, and it's a sign of strength NOT weakness. That's hard to come to terms with especially for Kiwi men and others from pioneering stock who were taught to most value, self-sufficiency and D.I.Y. ingenuity; and for those who take pride in being able to 'do it all'. The truth was obvious that what Moses was doing wasn't good for him or for the people depending on him - he was heading for burnout. As a leader it is easy to overestimate your own importance and competence. That's why the apostle Paul cautioned:

As God’s messenger I give each of you God’s warning: Be honest in your estimate of yourselves, measuring your value by how much faith God has given you.- Romans 12:3

God has placed people around you who have certain gifts and talents. When you recognize and involve these people, they're fulfilled and the job gets done right. God created us to be interdependent not independent. Delegating authority to the right people strengthened Moses for the task of leading as God intended. When you try to be 'all things to all people', you end up frustrated. You're not called to do it all, but to get it done through others. That's what leadership is about. Often the one problem with that today is that workmen are worth their wages and you have to also have the resources to $$$ for the assistance. Make an honest assessment, and put it before the Lord, pray for him to provide the right people and the resources to pay them, before you begin any project. It was the one problem Moses didn't have with his Human Resource rich people group at the time. The people who ended up helping him got paid in status!
