When you first start out and earning an income is your priority - especially if you consider the amount of music you need to compose to make a good living - it’s very tempting to work every hour of every day and right through weekends.
Have a strong work ethic is essential, and composing quality music at a productive speed will stand you in good stead for the future; however, it is easy to fall into the trap of music not only being your life but taking over your life.
The most important consideration is balance. Make sure you get out of the studio, go for a walk, go to the gym, get sunlight on your skin.
