Incidentally, helping others grow their wealth is also a good way to grow your own financial worth as a side business idea. If you have stock market and finance credentials, then you can earn freelance commissions or consulting fees, advising clients on how to get the best returns for their investments as a lucrative side business idea if you can get results for those clients—otherwise this business idea can be the fast-track to alienating friends and family, so be careful.
What will also help your earning potential is to specialize in one style of writing, and maybe even one particular subject. You see, writing on the same subject for hundreds of hours each year makes you an expert on it. To paraphrase Cal Newport, “…you'll build up a lot of career capital through deliberate practice.” It’s how you become so good that clients can’t ignore you.
Persistence and Commitment. You’ll need to have a good amount of persistence while pursuing freelance writing gigs. This business is subjective, and while one person may love your writing, another may not. Do your best to always produce good, solid copy and hold on to your commitment to do the best you can for your clients. Just by committing to do those two things, you’ll be miles ahead of your competition.
Mobile applications are more popular than ever, and people are willing to pay good money for ways to manage their lives from their smartphones. If you have a great idea and happen to know coding, you can run with it and create your app yourself. If you just have an idea and don't know the ins and outs of how to turn it into a reality, there are plenty of software developers looking to collaborate with people on app creation.
