You have a duty - and that is to be true to your inclinations and desires!

We so often fear doing something that we are really called to do in the concern over the other people that may be affected by our choice.

What we are not acknowledging, is that there is always a perfect plan in motion. 
You will never know the outcome of any of the actions you choose to take, but you can trust that it WILL turn out great for everybody else affected.

When you have a strong, sincere desire to do something, do it. 
You are a part of something bigger (always), and by taking action on YOUR part, you open up the magic for ANOTHER'S part.

This works the other way around too.
When somebody takes an action that affects you, even though it may not seem comfortable from your current viewpoint, know that everything happens FOR you.
There was a reason that somebody had to do that something.

You will lessen your frustration  remarkably when you acknowledge this wise truth.
