When linking texts, you have to consider what they have in common in relation to potential ideas. To show this, use words that signify that you are linking, especially between paragraphs.
For example (I haven't learnt journeys yet, but still consider):
....thus it shows that a journey itself is more important than the arrival because of such experiences.
===> With experience comes discovery and learning, and people can learn more about themselves through journey as shown in.........
You can link in terms of logical flow of ideas, which I think is the best way to do so. You can also link in other ways such as through common techniques, context, etc.
As for linking back to the question, you should always come back to the THESIS and the question when you have finished a paragraph or when you have finished explaining one idea. This helps reinforce your argument. Don't repeat your thesis everytime, but rather reword it or write it at a different angle in each paragraph.
