I am 25, and planning on going in real estate because it seems like hard work in that business pays off compared to other places and because I am very persuasive.
Also someone suggested to me I should get insurance..220 license ,real estate, mortgage license? can someone explain to me what all that does?

Pick how you want to be in real estate. Do you want to become a REALTOR or investor? If REALTOR, align yourself with the most effective sales company around.
Also, implement a prospecting system as quickly as possible.The most successful investors buy property at significant discounts and then sell them at a very big profit. Learn about pre-foreclosure, foreclosure, short-sales, rent to own and other investor programs to make a lot of money without investing any of your own. If you choose this route, find a mentor that has an effective system and learn from them. If you have a sales personality, fortunes can be made investing in this type of real estate. Also, making money through this type of investment just requires tenacity and an understanding of sales. I know a number of millionaires that started investing in real estate at a young age.

Buy property/never rent.
2 free classes. sleep. [I'm kidding!] Use this time to prepare yourself to what kind of standards you are looking for in your future investments. Take classes that help you depending on whether you're going to be an agent or a private investor.[not your actual job]. Possibly a speech &debate type class work on your speaking/ also being able to work with a property's location, etc. is extremely important and you should take research/internet classes possibly, too.
Just do the Donald Trump thing:D

The more you're able to read and relate to people, speak with or in front of strangers, market a product or fill a need, compute numbers and realize the financial benefit from both short term and long term financing, the more successful you will become.

Good luck and you're right, it is hard work but it is also rewarding in so many ways.

Ask the same question to 100 real estate pros and you'll get 100 different answers. I would say to educate yourself about various aspects of the industry by reading about them online and really running with the one that seems the most interesting to you.  Over the years, as you learn more and more about that aspect, you will be proxy pick up bits and pieces about many of the other ways you can be involved.

I started out buying a rental property and learning how to  be a great landlord.  I love rental income!
