In my experience, one of the greatest challenges people face is deciding why they are starting a business, what they hope to accomplish and what they really want to do. Starting a business, particularly from home, sounds glamorous and free but, in reality, it can put a strain on home life if not done right. People I talk to often need help decision-making which is an essential quality in running a business.
I have another to add to your list that’s almost as easy to do as going for a daily walk! Clean up litter outside commercial properties for property management companies. The work is done on foot using simple hand tools. I started this as a side gig in 1981 and grew it into a profitable full-time business that I continue to operate today. I share my experience in my book, Cleanlots, and offer free support.
Starting a business in this field will require some experience, but as long as there is anxiety, there will be a market for coaching people to create and deliver presentations. Invest in video equipment or use a smartphone to record students as part of the coaching process. If you have a background in radio or TV or specific experience in high-profile public speaking, all the better.
A great way to come up with a business idea is to brainstorm about your existing skills. Focus on identifying the skills that are unique to you or that you particularly excel at. Evaluating your previous professional experiences should give you a hint. Think of instances in which you were able to provide value to the organization for which you worked: do you notice any trends?
