Keeping your shit together

It's a good concept. In theory. The concept of having your shit together is broad and signifies various things to different individuals, but it's generally a mixture of being stable:
Financially (i.e. spending under control, saving money, no 'bad debt', on pace with paying off 'good debt', regular income)
Physically (i.e. eating correctly, exercising, avoiding/limiting alcohol and other drugs, in excellent general health)
Mentally (i.e. joyful, pleased, not depressed, accepting of oneself, confident, self-assured)
