Shipping. You will only have a few days to ship a book after it sells, and even less time if you agree to include two-day or overnight shipping as part of your options. And since you’ll want to save as much as you can on the shipping, you’ll have to devise a plan. Many people set aside specific days for shipping – say 3 days a week – and then make one big trip to the post office. As long as there isn’t anything else in the package, you can send books via media mail, which is the least expensive option. Finally, your books will need to be packaged in a way that they won’t get damaged in transit.
Don’t do everything. People often have wrong mindsets when it comes to freelancing. They think they can earn more money when they receive more work order. It is essential to stick with your competencies and prioritize only the work that will help to bring in more assignments. Do a good job, leave your clients happy, work with other freelancers and develop a network of people who will recommend you and send work your way.
One thing, though, there is a big difference in making an app for Android and an app for iOS, and that is the fact that making an app for Google Play costs just 25$ one-off, making an app for iOS costs 99$ a year, so if you are making an app for iOS, I will recommend you to be a bit more confident about the way you will make money by your app, than if you are making an app for Android.
Note: There are dozens of other survey sites out there. These just happen to be the more well-known ones that have a reputation for paying out in a timely manner and not having impossible standards for cashing out. As always, be careful with your personal information. I recommend using an entirely separate email address for survey sites so they don’t clutter your inbox.
