My advice to you is to take things one step at a time.

The secret of people who have achieved what you've longed for is that they start doing it little by little.

For example, to visit another country, start by researching the requirements, then gradually gather each requirement. Then the money, and then, before you know it, you're already visiting the country of your dreams.

Start doing things, because we regret what we don't do more than what we do.

Go! You can do it!
