First forget all the bad things that had happened in the past. Start fresh.
Next try to get involved in your local community work like bake sales or fundraising events. Try getting involved in your schools events like debating, school council and so on.
Try to help others, be honest, be kind and considerate and share but not too much because if u share too much then ppl take advantage of you.
Study to improve your knowledge and your grades.
Try different music styles, clothes, movie selection or foods.
Be very hygienic and fresh.
Enjoy holidays like you are having the time of your lives.
