Pros and cons of Traveling the world in your 20s

Traveling the world in your 20s
 I thought that traveling is great and  it´s funnier to travel when  you´re grown , but as all good it has something good and bad.
The plusses of my topic are:
First, you decide what to do and where to go, because nobody is taking care, you are taking care of your own.
Second, tourist places are the best, but also some people have a better idea, they are known as "mochilero", that kind of people meet other people and make new friendships with natives.
Then there´s, people who travel and they visited abroad, obviously cities and famous places are visited by those people.
Finally, I hope some day, I will take that oportunitie.
And cons are:
The minuses of my topic are:
Above all, money are, basically, the most important and as always you will need so much money.
But there is also, you need time, but in this troubled life, no all the people have it.
Then again, security, it´s not safe to travel alone, however it is a lower risk.
In conclusion, it is good to travel and it is awesome, anyway travel is dangerous if you don´t know where to go.
