Too many how to questions

Recently, this idea occurred to me: I have being asking too many how to questions in the past. How can I solve this problem? How to improve my test results? How to be a good parent? How to better raise my children. I rarely spend time on questions what and who questions. Who am I? What have I done? How do you feel right now?

I started to realize that some problems can never be solved just by asking how to questions, for example: how to be a good parent? By asking this question, one is likely to get tons of suggestions, most of which may seem easy to follow, but once you try to put them into practice, you may find if the suggestion contradicts with your personality or instinct and it becomes almost impossible to apply them. What are the root causes for this problem?

It because I have not found the answer to what kind of person I am. Looking into myself is more important.
