Importance of Travelling is that-
Provides learning and education about places and history. Connects us to other cultures and people. Slows us down: Gives us a break from our fast-paced lives. Expands our awareness and introduces us to greater diversity. Helps us break habits: mentally, physically, and emotionally. Gives us time to heal, reduces stress and helps us regain enthusiasm for life
.Stokes curiosity and awakens our inner child by offering us new, “first-time” experiences. Promotes patience by releasing heavy expectations of the “one right way” mentality thereby allowing life to flow more organically. Invites the opportunity to get lost and face one’s fears of the unknown. Helps you get to know yourself better: the true you is rediscovered
