There is a low correlation between success at work and happiness.
Enduring happiness arises from aligning your actions with your values. Success on the other hand is the result of goal achievements. If your goals don’t reflect your values you will be disappointed in their achievement. Work will be exhausting. Life will be frustrating. But it’s not life that is disappointing. Rather, it’s that we have gotten confused as to its purpose.
Know what makes life meaningful to you. That’s your calling. Pursue that.
Your life may not be easy, but it will be worth it.
