The business took off more than expected. The business is going much slower than expected. My spouse or a personal issue is making it very stressful to put the time and commitment I need into my business.
These are just some of the causes of a common malady afflicting entrepreneurs: just plain exhaustion. How do prevent it when things risk creating unbearable weariness? Sit down and adjust your plan. Take a serious break. Rely more on others to take on some of the load.
If these don’t work, and you simply can’t take it any more due to dreaded burnout, consider selling the company, remaining the key shareholder but become completely inactive, or simply shutting it down. Sometimes the hardest thing to accept is when you just don’t have it any more and you do not want to continue.
