One of the issues that do affect the freelancers is that they do spend much on buying tools. This has really affected the performance of some freelancers and even reduce their personal profits. Freelancers should make sure that they are not spending much on buying tools. They can easily buy those they are free trial to get their cost cut. Money should not be wasted on buying pro version of the tools. What do you think about this?
