I have always enjoyed working alone unless when it is time to outsource the jobs that I have at hand. I know that there are times when I will need help and all it will take is outsourcing the jobs so as to get it done as fast as possible. Aside that, I prefer to complete the jobs that I do alone.
The most important thing is for you to know when it's more convenient for you to work alone and maximize your earning and also know when it's the right time for you to seek extra hands for the job that you have at hands. It's the only way you can be able to meet up.
