travelling

When you are a student, you have the time and energy to travel, but you have no money.

When you are working, you have the money and energy, but you have no time.

When you are old and retired, you have the time and money, but you may not have anymore energy.

So when is the best time to travel?
I would say, every time of your life. Because you experience and observe different things at different stages of your life.

So save up, manage your time well, and keep fit! :)
