Unless you are extremely lucky, you have probably felt the change in the last decade related to the global financial crisis.

Most of us are still feeling the effects, as current wage growth is not close to inflation.

With the difference between income and living expenses, which increases with each payment, many people are looking for ways to supplement their income. And logically, but if you do not have free time for a second job, it is not easy. There is not much time left for full-time work, raising children and little free time for yourself.

But what if you could make a little more Money without having to give up a lot of your valuable time? Better yet, what if you could do it with minimal cost and effort? Maybe you can even do it from home. Here are five realistic ideas on how to make a little more money at home or in your spare time.

1. Sell your stuff

Selling things you no longer want not only leads to extra money, but there is a bonus to clearing your home - and this is extra space that you can use for other ways to make money.

Sports equipment - have you ever really used the exercise bike you bought? Have you ever wondered what other unnecessary sports items you have? If you really use them once every few years, you may gain more if you sell them. 

Children's clothes are shrinking so fast that you can post unnecessary clothes for sale on the Internet. Until you feel it and you have to buy 2 sizes bigger shoes. All baby things like strollers, highchairs, kangaroos, etc. are sold easily because there is also demand. Just make sure everything is clean.

2. Teach

A great way to make extra money is by selling your knowledge, skills or experience through teaching. This can be something from your professional life or teaching others your hobbies.

You can conduct successful lessons in individual training or for small groups: yoga, cooking lessons or music lessons. It depends on what you teach, but all you need is some equipment or space and these costs can be covered by the money you make. For some things, such as exercise, make sure you are insured.

3. Create and sell

If you are lucky enough to be a creative person, you may be able to make money from your craft hobbies. A quick glance on the internet shows that thousands of people do things and sell them. Many people even do this full time.

Some of the arts and crafts you can enjoy are, for example, decorations and invitations for wedding tables, parties, T-shirt designs, jewelry, knitwear, custom furniture and original works of art.

There are many places to sell your creations online, such as Facebook, OLX, or even your own website / blog. Why not join the various art and hand-made festivals that are organized.

4. Offer a room at AirBnB

If you live in a busy city and have a free place, why not try AirBnB? You can equip the room with second-hand furniture at little cost and earn extra money each month. And you can meet new people from foreign countries.

5. Become a mystery shopper

Mystery shoppers are paid to visit stores and report back on the customer service they experience. How much you get will vary a lot, but your costs are covered, so you can usually keep what you buy! Mystery shoppers visit restaurants and report on the quality of food and service. And free food is never a bad thing!

You have to be very observant and have a good memory to be a good mystery shopper. You will need to remember your short questions, ask questions and be able to remember the names of the employees who have served you or describe them accurately.
