There is a great philosophy presented Lama Surya Das in his book, Buddha Standard Time. He speaks about the importance of not keeping each fish you catch metaphorically, but holding onto the big fish that you truly seek. Would you recognize the big fish you are seeking if you caught it? Are you easily distracted but whatever pulls on your line?
“The little fish are our momentary desires, ambitions, and goals: fortune, fame, pleasure, comfort, and other fleeting experiences. None of these can last. Yet we cling to them as if they will endure forever. The big fish is finding our eternal dream. Too many people fail to find the overarching purpose of their lives.” -Lama Surya Das
