You could add the prefix "mis", which basically means wrong or unsuitabe. Then, you would have the word "misconception", a wrong or erroneous belief. :)
A prefix is a letter or group of letters added to the beginning of a word with the intention of altering its meaning by forming a different word. The prefix that is added to the noun "conception" to transform its meaning into "a wrong or erroneous belief" is mis-. The word then becomes "misconception".
The prefix mis- comes from Middle English and means wrong, bad, or erroneous, as well as lack of. For instance: misunderstanding; misfortune; misspelling; mistreat; mislead; mistrust.
I would say (You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life) Have a nice day Hope this helps !!!!
