What should i improve about myself, do i have potential?

Thank you, what would be a good example of making my hair thinner and trimming the edges. Should I try to cut my hair with siccors or go to a hair salon?
Definitely see a professional hair stylist or visit a local salon, especially if you're already unsure of what needs to be done. They'll be able to assess your hair properly and recommend how much bulk to remove and from where it should be trimmed. I wouldn't suggest cutting it yourself without prior experience, since its quite easy to take off more than intended.
