There are very few things that will allow you to spend your time passionately, and create a better future for yourself simultaneously.
Investing in yourself is one of them. You don't have to turn every hobby into a business, but putting time, money and energy into learning a new skill, or improving an old one is invaluable. It may turn into something that is profitable, or it may just give you the sense of peace you've been searching for.
Whatever lights you up, throw money into that.
Whatever brings you child-like joy, spend time doing that.
Whatever helps you be connected, please pour energy into that.
It is not selfish. It is essential.
It is showing the world that you value yourself, your happiness and your mental health. Everything will change. The shift may be so subtle that you don't even notice it. But because you've declared that you are worth that time and space, all the rewards of self love will head to you.
