There are advantages and disadvantages to being a solo professional who owns and operates their own business. One of the disadvantages is that you might become so involved in the work that you don't consider the ways that you can grow or expand the business.
Do not fret, however. There are many ways that you can expand your vision and your mind:
1. Attend conferences and workshops - Make sure that you have a creative Professional Development plan that you can enjoy each year. You might want to register for events that are sponsored by the organizations where you have memberships or those which are designed for other professionals in your chosen niche. Do not, however, rule out going outside what you might normally do. For example, if you are a dentist, you might decide to attend a seminar on computer technology or creating information products. Learning new skills and gaining knowledge in a number of areas will keep your mind working as you apply the concepts to your practice.
2. Subscribe to interesting magazines and journals - The cutting edge technology and new ideas being introduced into society will be documented by publishers and you can benefit from the work of others by merely reading about what they have done.
3. Develop relationships with interesting people - It really doesn't matter what experience or training they have. You can learn and be encouraged by an enterprising teen or a retired senior. The important thing is that you are willing to share time with people, ask good questions and listen carefully to the answers.
4. Travel - One of the very best ways to gain perspective is to enter a culture that is relatively new to you. Often, when you are away from your business you will be able to discover answers to problems that your mind didn't have the freedom to work on while you were so occupied in your regular setting. You might visit a professional in the country you are visiting and acquire a brand new idea that you can implement when you return. Besides this, you will likely benefit from the rest and environment so that you can give your mind and body the break that will help you return with as a refreshed individual.
Routine is important and consistency not only reduces stress and develops confidence but if you don't keep learning and expanding your mind, over time you might become boring and bored. It is up to you to find ways to keep yourself and your business open to new ideas.
