When it becomes a burden, it’s not a passion. It probably never was.
You can take a break from it, hoping to recharge the passion batteries. But when you go back to it, it will only drain you again – it’s a burden.
If something becomes a burden, it is a lead indicator you are not doing your passion.
I am not suggesting that you shouldn’t take on tasks that are burdens. Entrepreneurs have to.
What I am saying is that many activities drain us, and a few (very few) energize us.
Your life’s vocation needs to be in doing what gives us energy – doing your passion. And the best way to finding your passion, is to recognize the things that have become a burden.
