Do you have personal goals you’ve been working for a long time to accomplish? What are they? How do you stay motivated?

A personal goal i been trying to accomplish is to stop biting my nails. I been biting them since i was young and its hard to stop. Biting my nails is a bad habit that i always try to contain and recently i think i am slowly stopping. i been staying motivated by concentrating on other thing and when i look at my nails i want them to grow so i try and stay busy.
