Travel Solo at least once.
Usually, Humans tend to travel with a companion or group of people, however, you tend to miss out many interesting places which you like as the other person or the group of people would choose and you would be regretting it.
Travelling solo helps you to explore a new place or new destination and also you can visit the place which you like rather than being dependent on any others. Travelling solo will help you to be independent, face many hurdles and also will make you open up to new people on your journey.
Travelling solo has helped me many ways, where I have visited some places which I never dreamt of visiting when I travel with a group, taking spot decisions and also meet many people through the length of my journey which I would have never experienced If I had visited in the group. It made me learn about myself, my strengths and weakness. But a plus point, I visited not so touristic locations.
You will learn life skills like not dependent on others, decision-maker, planning etc which you never get to experience if you go via a tour operator or with a known group of people.
