I'm going to ignore people who are trying to lecture me
That makes me feel bad. Why are you going to ignore them?
Because I do not like being lectured
What you perceive as lecturing may just be someone caring enough to try to help you. You are being too quick to judge a person's intentions. You should be more understanding of the intentions of others.
Nah. I hate people who are trying to lecture me, it's annoying when people think they can talk down to me.
I feel like your reactions towards people in your life is a little bit misguided. As I have said, they are for you and they're not lectures - they're means to make you be a better person. I hope you keep it all to heart and listen to everything they tell you.
