This will provide you with a chance to get to the destination with lesser stress of the travel.
Get Used to the Route
Get accustomed to the route on which you travel. There are going to be some interesting sites on the way and look forward to catching a glimpse of them. Besides you can take the whole experience as a learning curve since you are getting a chance to see places and learn about them.
A lot of the times, the experience is not as bad as you may think. It is important that you take a positive look at things and appreciate the time and cost the public transport is saving us. Doing so will create a positive mindset about the experience and you will feel rather well.
There are many activities that you can do. One of them is reading books if you like to do that. You can also listen to music or play games on your phone to keep yourself busy and feel better about the journey that may not be very pleasant otherwise.
There are always people who are travelling at the same time as you are. It is not a bad idea to be friends with someone who is similar in nature to you and you can connect with the person. A bit of chit chat can make your journey all that much easier.
