If the problem you are solving is more important than the solution you have proposed, you are on the right track. Be married to solving a problem, not married to one solution.
When you get up each day, focus on being a better manager, a better team leader, and an inspiration to your team.
Remind yourself why you decided to solve the problem in the first place to not feel too concerned about the tasks of one day. A life of service reaps many rewards for your soul, and eventually your bank account. :)
