The obligation to do something is not the problem. The problem is your anxiety about it.
The responsibility you have is not the problem. The problem is your resentment of it.
Instead of trying to avoid obligations and responsibilities, focus on their benefits. They burden you only to the degree you see them as burdens.
Following through on your obligations will earn you respect. Upholding your responsibilities will give you influence with others.
Every person has a desire to matter, to make a difference. Obligations and responsibilities enable you to make a difference in a meaningful, positive way.
Choose to stop fighting, stop worrying, stop complaining about obligations and responsibilities. Embrace the great richness they can bring.
