I find that so much of what is true ‘happiness’ in one’s job is how we conduct ourselves and our thinking.
For example, even if your job isn’t your exact ideal, there are elements that can bring full happiness. Being of service is not relegated to any one sector. Being professional, kind, courteous, and with a high “client service” attitude to external parties as well as to the internal team, can bring high “happiness” value.
Ideally, it should be coupled with sincere appreciation in return. Regardless, it makes us feel happy to deliver sincere value. We hold a “high happiness quotient” in our own esteem for ourselves and how we are serving.
On the larger scale of trying to find something you love to do–I do think each person has a wonderful contribution in life and is here for a reason. That doesn’t mean you don’t have to search for it. Part of the searching makes us who we are; hones our goals; and positively affects others along the way… Life is not just an end game of finding the one job which makes you happy. You are evolving, and your happiness, and therefore growth, is also evolving.
