What you really need

You were always this scavenger in the desert,
Ever readily sourcing for water
One day you stumbled upon this huge oasis
Which contained all the water you needed
Pretty and inviting at the same time

You couldn't wait but run towards it
Drinking all the water it had to quench your thirst
Simply failing to notice the cactuses standing around it
Also holding the fluid you wanted

The sharp thorns turned you off,
And your immediate need blinded you
Should you have been more patient to extract
Whatever water there was within the green thorny plant
You would have realized

What was inside, was what you actually needed.
