This analogy makes a lot of sense:
A bottle of water at Costco or Sam's Club is 25 cents
The same brand of bottled water, the same size, is sold at the grocery store for about 50 cents
The exact same bottle of water at a bar costs $2
At a good restaurant or hotel, that bottle of water can be $3
And at the airport - wow - that same bottle of water, the same brand from the same bottling plant is probably $5 or more!!
The only thing to change about this bottle of water is the location where it's being sold. Each location places a different value on the bottle of water.
When you feel like you're worth nothing, the people around you don't see your value - change your location!
Having the courage to make a change and go to a place where your contributions are valued makes all the difference. Surround yourself with coworkers who really appreciate what you bring to the table.
Don't settle for less.
