Life requires us to learn many skills. We may become quite good at some of them; have a real talent for them. Receive money and praise for them. And yet, the skill is not our gift.
How to tell the difference. From my own experience, I'd say the main difference is that working hard using my skills leaves me tired and drained, but working hard using my gifts leaves me tired and fulfilled.
As you answer the questionnaire and reflect on your life experience, it is important to ask, "What gives me true inner satisfaction and joy."
When answering the questionnaire, pay attention when the question is about, "I enjoy ..." If you do not actually enjoy the activity, then rate it low even though you may be praised for it and do it often.
