Many people start a business hoping to improve their work-life balance. But in the early stages, particularly, running a business can be an all-consuming venture.
It's likely that you'll have to sacrifice some of your social activities, for a time at least.
The final call in most business decisions will rest with you. This can be one of the most rewarding aspects of being your own boss, but it's a high-pressure position to be in.
If you're an employee, most of the decisions you're faced with will be within your area of expertise. But, as an owner-manager, you'll have to be ready to deal with every area of your business, from sales and marketing to finance and HR.
The potentially serious consequences of your decisions can be another source of pressure when you run your own business.
The success of your business - and your livelihood and that of your employees - can depend on your course of action from week to week.
It's easy to focus on the exciting aspects of starting a business. But the flipside of being your own boss is that in the early days you'll probably also be your own receptionist, admin assistant and book-keeper.
And there are red-tape obligations - forms to be filed, records to be kept and rules to be learned and followed.
Running your own business can be an immensely rewarding experience, giving you a real sense of control over your working life, as well as clear potential financial gains if you can turn your idea into a successful operation.
Make sure you have a clear understanding of the requirements of the business sector you'll be working in.
If you have worked in the same sector previously, this shouldn't be a problem. But if you're moving into an area that's new to you, do your research. You might want to look at training, or hiring an experienced staff member.
Being half-hearted isn't an option. If you are going to start your business you have to give it all you've got.
Can you keep plugging away even when things aren't going your way?
It's crucial that you believe in what you're doing, because you'll have to convince others - such as your bank manager - to support you.
Running a business can be lonely, particularly in the early stages.
There'll be no one looking over your shoulder to make sure you get things done. You'll have to rely on your own motivation and self-discipline.
Being your own boss isn't all about independence and autonomy. You might have more direct contact with suppliers and customers than ever before, so being able to form good business relationships is an important skill.
As your business expands you will also need to be able to share responsibility and delegate tasks to others.
Successful entrepreneurs are generally comfortable taking advice and are happy changing their approach if a better one is pointed out.
People who start their own businesses benefit from being resilient, patient and realistic. Make sure you are prepared for the fact that you are unlikely to become a millionaire overnight.
Family can be a great source of moral support for someone starting out in business. Keep them up to date with how things are progressing.
Make sure that everyone understands and accepts any significant changes your going into business might involve for them. Your schedule might be busier, for instance, or your income less predictable in the early days.
Your friends will also be an important source of support.
If you know people who have experience of running a business or know the sector you'll be operating in, ask for their advice.
There's a wide range of business support available that can ease the process of starting out in business. These include professional advisers from organisations such as Business Link and Enterprise Agencies.
Business mentoring is another option - this involves experienced entrepreneurs providing ongoing help and advice to start-up businesses.
Local business networking groups provide a forum where you can share problems and ideas with other business owners.
Check whether there are any online communities matching your background or type of business.

Do you have the money you'll need to get your business going until revenues start to grow? If not, where will you get it?
If you'll be giving up a regular wage to start your business, do you have the flexibility to cope with possible fluctuations in your income?
Which is more important to you - safeguarding your financial security or seeing your business grow?
Make sure your strategy for your business reflects your financial priorities.
If your business plans place others at financial risk, make sure they understand the risks and accept them.
Worrying that your business won't succeed is perfectly natural. It makes sense to think about how you would respond if your business were to fail.
But if your fear is more intractable than this - if it continues to undermine your work and confidence - then starting your own business may not be the most rewarding course to take.
Once you've assessed your skills and your situation, don't be surprised or disappointed if there are areas of weakness.
The important thing is to acknowledge these fully and to see how you can overcome them. There is a wide range of support available - from family and friends to banks and business-support organisations.
Few people know everything about running a business before they start.
Most things you can pick up as you go along - though you should be ready for a steep learning curve.
Remember - take advice and learn from others whenever you can.
