I'm pretty conservative. I believe that buying good quality is a good investment. I buy fewer things but of better quality.
No matter how busy I get or how much pressure is on my shoulders, a good workout makes me feel at ease. I come off the treadmill feeling relaxed, full of joy and with a sense of perspective over the issues on my plate.
The fears you do not face become your walls. Most people in business, and in their personal lives, design everything so they can avoid doing what makes them feel uncomfortable. Yet any good business person knows we are not only paid to work, but also we are paid to be scared.
I take a massage each week. This isn't an indulgence, it's an investment in your full creative expression/productivity/passion and sustained good health.
