You raised a very good question here @yatin401
Traveling solo teaches you so many things. You learn to be independent and take full responsibility for your own actions. You learn to think on the go and resolve any issues quickly.
Especially as a female solo traveler, I've learnt to be alert but not too stressed out at the same time. You also learn how to adapt to the people of different cultures, how to make connections and friendships, and at the same time how to be on your own.
As @googolgoutham mentioned, lone traveling is a great time for self-discovery. You have to face a lot of your flaws and be able to accept and deal with them.
