3. Travellers know things can go wrong.
Travellers might travel on their own. They can also invite their mates to join them. In either case there's no guarantee that absolutely everything will go right. A good traveller will always be ready for the unexpected. Unpleasant surprises can happen on the way and then he/she will have to adjust or rearrange the plans. No matter how good a traveller is at planning ahead, life cannot be predicted. Travellers are always ready to change and adapt to the current situation and do not feel frustrated when things go wrong. As you can see, whose who travel usually have strong personalities.
