Hi there,

Part time jobs acts as a savior at the time when doing regular jobs are at risk. Maintain both jobs isn't  easy as an individual has to balance the sincerity in both type of jobs. Failure in any can lead to debarred so better to look for consistency and peace than earning.

Talking about your point of selecting a niche for freelancing. See, freelancing can be done in anything and in almost any field. See, for freelancing, it is important to have a particular skill that will help you to earn as well by giving you more and more opportunities.  Also, j would suggest you to improve and select a particular skill that will ensure you to work better.

Field in which you are interested and can work on any level is the topic you need for freelancing. Also, learn more to earn more.

Hope this helps

Thanks!!
