You could also opt to use existing websites for making money. These include both active income and passive income methods. For example, you could sell some used items or invest in creating some digital designs that then can be sold on merchandise. Again, devote a sizable portion of your time to passive income so that you can slowly build up earnings that will arrive on autopilot without any extra added effort. 
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)

Set up a professional invoicing system and send invoices either bi-monthly or monthly. Use your computer software’s invoicing templates or you can create an invoice using Excel. Decided when you plan to bill and be sure you send invoices on the same day of the month to ensure consistent payment. Institute a 10 day late policy, if possible, to make sure payment is received promptly.
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
Decluttr is easy to use. Grab an unwanted item, check that Decluttr buys it (for instance: CDs are great, old clothing is not), and enter its barcode into Decluttr’s “valuation engine” or use your Decluttr smartphone app (iOS and Android) to scan your item directly. You’ll receive an instant price quote that you can accept or decline with no obligation. If you accept, just pack your items into a box large enough to fit them, slap a free Decluttr shipping label on it, and bring it to any authorized UPS location (including drop boxes, if your box contains fewer than 25 items). Decluttr issues your payment the day after your item arrives by PayPal, direct deposit, or paper check. There’s no practical limit to the number of items you can sell: each order is technically limited to 500 items, but you can create as many orders as you like in any given timeframe.
