Gratitude is one of the strongest and most transformative states of being. It shifts your perspective from lack to abundance and allows you to focus on the good in your life, which in turn pulls more goodness into your reality.
If the point of an activity is to be relaxing, changing that point to money isn't a great idea. Then you have to show up for it differently, and that can take the fun out of it, absolutely. I'm a big fan of turning your hobbies into businesses, but not if it's the hobby you do to relax and unplug.
Try new things, step out of your comfort zone, take risks, do things in ways you've never done them before, ask for help, surround yourself with self-actualized people, become obsessed with the fact that you have one go-round on this planet as the you that is you, and realize how precious and important it is not to squander that.
If something bothers you, focus on the solution or the desired outcome, not the part that has you spinning out in the middle of the night.
When you understand that making, saving, and spending money is all based on the thoughts you're thinking and the actions that these thoughts lead to, you can completely transform your reality - and your bank account.
