For example, I might start: “Being true to yourself is very important in the long run, but in the short run it can be really hard. ” (Then explain why it’s important, then give the example of where it was really hard, then conclude.)

For your other topic, a beginning might be: “I used to think it was best to deny my feelings, especially if I didn’t like what the feeling was. But now I know better.”

I hope you understand these are just ideas of how to approach the subject — they may not fit your thoughts at all.

The important part is to get the reader interested. Don’t start with a philosophical discussion, start with what the subject means to you.
