Part of the Business
Most business owners second guess themselves, especially when business slows down or unforeseen events occur. Instead of stressing over it, you have to keep moving forward. Find new ways to retain customers/clients, expand to meet increasing demands, and get additional training if you're lacking in any areas. Only after you do these things should you really consider shutting your business down.
You should also understand that uncertainty lurks in every business decision you make. But if you don't make these decisions, you could lose what you've worked hard for.
Weigh Your Options, Make Good Decisions
There's nothing wrong with taking some time to weigh important decisions. Every good business owner does that. When contemplating a new direction, try not to let uncertainty make decisions for you. Look at the hard facts – numbers, competition, labor, cost of expansion, etc. Consider how much time you have to devote to expanding or increasing your client base.
Being Uncertain Isn't a Bad Thing
Uncertainty isn't a bad thing. And since you may always feel uncertain about some part of your business, it's best to just accept it than try to change how you feel. All businesses take time to grow – some become huge successes, some see a little success, and some don't. But failure to make important business decisions because of uncertainty will not help your business succeed. Make peace with uncertainty by finding ways to unwind after a long day – take up a new hobby, travel during your free time, make friends with other business owners, and continue to educate yourself. By doing these things, you will reduce feelings of uncertainty or at least learn how to deal with them in a more positive way.
